You asked me in another thread what conservative ideals I still hold. I didn't want to derail that thread, but since this one is a pointless circle jerk, it makes a good case study.
First, let's take the term snowflake. Snowflake specifically applies to the micro aggression periodic table of identity liberals who find a social cause or something offensive in even the most seemingly mundane of things. Those people are snowflakes. That some on the left are now trying to reverse use of the word is just lazy and cliche. The Infowars guy is many things. Going after a young adult the way he did, I would say @sshole or bully would be a better descriptor. As a conservative who believes in treating others with respect, he crossed a line. He is not however, a snowflake. Conservatives may play the victim card but not out of some foolish notion of uniqueness.
Now let's take the OP's title. Liberals are champions of gender equality, yet the OP felt it necessary to point out it was a little girl. Now why is that relevant? Is the ownage more significant because a little girl mouthed off to an adult male? What if it was a young male mouthing off to an adult male, would it be as funny? Seems a bit hypocritical.
As for parenting, both the instigator and response are the results of bad parenting, or failing education, or an increasingly uncivil society. Take your pick.
