Theis issue with conservatives isn't the policy you believe in, the issue is that you are just so unbelievably ignorant of how the world works, to where you see an issue like migrants coming in, and think that its such a big problem that the best course of action is giving a flamethrower to a convicted felon rapist and likely a pedo (all the things you supposedly firmly stand against), and trusting him to burn just the right parts down with authoritative force (something you are also supposedly firmly against)
Furthermore, if you bothered to actually care, you would have paid attention, Dems completely would agree with you that undocumented migrants were a problem - Biden had a border bill that was bipartisan, supported by border patrol, that would have allocated all the correct funding to reign in the asylum process, which would have correctly filtered the people that were coming here to work, versus those taking advantage of the system. And consequently, Trump told the Republicans to vote against that bill because it would hurt his chances of getting elected.
So for people like you, it was never about the migrants - you don't actually care. It was always about racism and sexism. At least there isn't any questions about it anymore.
