Historically, it was great if you were a white male.
Word?
White male soldiers, American Civil War (620,000 died, almost all of them white men)
White male Civil War double amputee veteran (Roughly 60,000 amputations resulted from the war)
White male coal miners (almost all white men worked very hard, long hours and had no other option)
White male soldier dying in World War I (116,516 died, almost all of them white men)
Voting rights, property rights, slave ownership, segregation, gender inequality, etc.
Total deaths of American soldiers up through the Gulf War were 1,264,000. Almost all of them white men.
Historically, white men were doing back breaking labor for almost the entire day, with no weekend. Whether that was farming or carving out a homestead in the vast wilderness of America, or later on working on coal mines and factories. Women had very hard work in those days too, because raising children and keeping a house were much more difficult and time consuming in those days. Still, few people would choose to be in dangerous conditions like most men faced over being at home with their children.
All men only finally got the vote right around the time that universal registration for the draft went into effect. Well, not universal... I should say universal to men. All men getting the vote was seen as a right they were gaining by being subject to conscription. When women were granted it only a few years after that, they didn't have to purchase that same right through any sort of civil service obligation. They just got it, no strings attached. The United States has never even considered subjecting women to the draft.
The vast majority of southern whites did not own slaves. Only 1/4th of them did and 88% of those had 20 or fewer. The VAST majority of slaves who were ever taken out of Africa went to Muslim lands. Of the 10.7 million who crossed the Atlantic, only 388,000 went to North America. The vast majority went to Central and South America. An extremely tiny percentage of living whites in the US have slave owner ancestors. The majority of the last living slaves, when interviewed in the 1930's, expressed that they missed that time, and that it was a good situation for them.
Scots-Irish (whites) were the first slaves in the Americas. I've seen convincing info indicating that they have been the "most and longest enslaved peoples" in history. I'm not sure if that's true. I do know that even those who weren't technically slaves were often treated much worse than African slaves. I've also seen plenty of newspaper clippings from the 1800's about Irish for sale as slaves.
Slowly the white male privileges have either been equalized or done away with. I can see why they are hopping mad.
Men and women have always had complimentary roles and privileges, until recently. For the majority of both sexes through the majority of history, life was hard and miserable. Typically significantly harder on men. Men have always been viewed as the disposable gender who should die for their women, die for their country, give up their seat on the lifeboat, and generally jump into the meat grinder of society's needs obediently.
A tiny, tiny fraction of men AND women have held the reigns of power in all societies, including white societies, for all of history. What we'd now call the "1%" - it is incredibly ahistorical to act like all white men had that sort of privilege and power. Almost none did. The life of a wealthy woman was probably even more luxurious and carefree than that of a wealthy man, in most cases.
Men had a great deal of responsibility imposed by society on them to accompany whatever privileges they had. Supporting their family was not seen as optional. There was very little, if any, tolerance for men who didn't do so. Men would almost never get to see the family they supported, they were too busy supporting them. Oh and amusingly, there is a complaint nowadays that women weren't paid as much when they did work in coal mines too, but this of course ignores the fact that the men were lugging huge chunks of coal while the women were placing small ones onto a belt. Similarly, the modern myth of the "wage gap" is entirely smoke and mirrors. When career and life choices are controlled for, women actually make slightly more. They just don't tend to put everything else in their life on the back burner to pursue a career like men do.
Early feminists (suffragettes, etc) would engage in what was called the "white feather campaign" where they would approach young men in public who were not in uniform, and hand them white feathers to indite them as cowards. To publicly shame them. These were the women supposedly gunning for "equality" but they never made a peep about wanting to be eligible for the draft or any sort of similar civil service obligation. This was particularly prominent in World War I, but also in other wars. Imagine being a terrified 17 year old boy in public, and having young women do that to you.
