Hrmm. You've never argued vs my friends then lol. To them it IS us vs them. I've had them ask me a question first, then I give my answer, and then they scoff at me and say it makes no sense. How can you reason with someone who literally cannot understand how a particle can have "spin" and have it not be like normal spin of a ball or something. I'm not making this up when I say this, but he says "That doesn't make any sense, they should call it something else. It just doesn't make sense that it could do that, so I don't think it is correct". Evidence? Doesn't matter. Math? Doesn't matter. My calm attitude? Doesn't matter.
And then comes the barrage of tiresome statements like: "Thats just a theory, they don't really know that", and "Well, if they are right, why can't they explain ____? They can't so they are wrong."
I find that people that are willing to listen to me and accept current scientific evidence don't give me those problems to begin with, so it's much easier, obviously.
To me it comes down to this. If they person is willing to listen to you and accept evidence, then go ahead and try to convince them or whatever you want to call it. If the person immediately goes on the defensive and shuts down to logical conversation, just pat them on the back and tell them that the evil demon fairies must have gotten into your brain last night.
