Honestly, what purpose did this post serve. He doesn’t want to debate or discuss with you.
Nothing you say will resonate with him. He wants exactly the response that you just gave him. He loves that he’s bothered you to the extent that you took the time to reply.
He will continue to post incendiary tweets and his own hateful ideas as long as people engage with him.
If nobody responds to it then he will eventually get bored and move on to troll libs somewhere else.
