IMO - you should just remove the 'funny' comments at the end entirely. If the point of the bot is to provide information in order to help people come to a greater understanding of the other person's perspective, then a joke about the person's political views isn't helping with that process. It comes off as making fun of a person's politics, and is making fun of a person's beliefs. You're directly linking common misconceptions and jokes made about people with political opinions to those people's political opinions i.e. you are reinforcing political stereotypes which does exactly the opposite of help people with different politics communicate.

The bot should just estimate the user's politics as best it can. I get your intent, I think, you were trying to make jokes to lighten things up or something? It was a good intention. I think this is a very good project and I thank you for all your hard work. But I also say leave the jokes out of it, they are hurting your hard work.
