This is getting pretty annoying on here.
Being that you can't figure it out on your own, let me spell it out for you.
The reason why he's bringing up his political views, it's because we conservatives are demonized by y'all, with your assumptions about how we behave and what we believe.
That is why he is going out of his way and being genuine with you that he will treat you with respect even though you both will disagree. I think that was pretty self-explanatory.
His point is to show you that just because he's conservative, that doesn't mean he's going to be a rude asshole to you because you don't believe what he does.
I am conservative as well, and after being on Reddit and just the internet alone and every social media site, we constantly have to prove to you that just because we're conservative doesn't mean we're a fucking asshole.
I'm still on reddit, reddit it's entirety is a left-leaning group think ecochamber. But I still use the website, and I constantly have to shift through leftist opinions even though I'm not subscribed to any political subreddits.
Quite honestly I would say it's something that conservatives have to deal with on every social media platform.
We have no choice but to coexist with you.
You claim to be tolerant, but your comment here shows the opposite.
