Thom's first post explicitly states that if you disagree with him, you are less well informed than him; and that you are an autocrat who does not accept dissent.
Thom's selfish and privileged expectation is that he can open with that attack, and that we'll all be polite and civil to him; even though he started the conversation by directly claiming that only dumb autocrats disagree with him. That's not how the world works though. Thom chose to be awful to a huge group of people; and he chose not to retract his shitty, awful words. he should expect people to treat him poorly.
Further, he's a white man who decided to tell a diverse group of people (who has never met) that we don't understand sexism or racism as well as he does. This was insane. The level of arrogance required to do this is... almost unmeasurable.
So a few things:
1) he shouldn't expect us to be polite. He was rude as FUCK in his opening, and he was also incredibly arrogant with his assertions about his understanding of american sexism and racism.
2) 'ad hominem' is not what you think it is. Don't use words you don't understand.
3) It's borderline insane for you to spend your life defending OP. ThomPete made REALLY bad decisions, and you have better things to do with your life than to defend a white male asshole who isn't actually being hurt at all.
4) The amount of "oh the poor rich white men who are suffering..." bullshit is off the charts. PG and Sama are suffering no harm at all, beyond a few words on Twitter. Their lives are completely intact. They're FUCKING FINE.
5) The people who will suffer in a DJT world are all powerless. They are people whose lives will not be completely intact. They are people who will be ruined. But you don't give a fuck aobut that because you're too busy vilifying people for being mean to an awful cunt like ThomPete.
