"They" are all the same then?
Do "They" all deserve the same fate?
That's the sentiment of the shooter.
Pro tip... groups of people are not monolithic. The outcome of different elections changes. You do not seem to understand or appreciate this so I will spell it out. Clinton was President. Then Bush. Then Obama. Then Trump. And you dare tell us it is hopeless to reach out and inspire voters? To change the outcome? To win an election?
Doesn't even have to be right wingers we reach out to and inspire. But it takes hope for a better future. It takes a tone of civility to reach out and inspire people in this way. So that you do not mis-communicate, trample sacred cows, or risk being see as threatening them or attacking them. Saying civility needs to end means hostility. Means there will be collateral damage among voters who could otherwise join you.
I view the subject as a matter of pushing people away, or reaching out to get them to join you.
I see a person telling me America is dead, and I see that they intend to push people away instead of building a better future.
