Read my post carefully. I'm not counting out sincere support for Trump. Obviously, polling shows that poor and working-class whites are a large share of his supporters.
That said, I would not count on there being many sincere Trump supporters on this forum. Most are... well, I think you know as well as I what they are like.
While I'm sure a few of the supporters are ironic, I would suspect that a lot of the TRUMP supporters here are like me, independents sick of the status quo who want to see Washington get shaken up. There's a certain joy I get out of watching TRUMP demolish a field of disgusting Republican candidates, from the establishment frauds to the fundie creeps. I'm less of a fan of him going after immigrants, BLM, women, and while I'm not a huge fan of Islam obviously BAN ALL MUSLIMS is taking it a bit too far. But let's be real, it's not like any of the other GOP candidates are any better than him on those issues, them and their supporters are just 10x more self-righteous and less self aware about it.
By unironically supporting him you do support it just through that alone.
