Arguing with who? If they can get you deflected by starting an argument about something else, that's on you. Just say "Lol nice Gish Gallop" and continue explaining the truth.

Here's an example of what I was talking about -- it's a little bit shooting fish in a barrel because the guy was pretty unpopular anyway, but I still felt it was worth articulating some of the positive-side talking points (not just "Biden's good I like him," which is easy to misconstrue into something, but specific tangible examples that are easy to get your head around). But, at the same time, calling out how silly the person's POV on it was. You can't get drawn into a back-and-forth, no; that side of it I do agree with. But if you're playing cards with someone and they're trying to cheat, it's absolutely okay to point out "hey he's cheating, this is how" as long as you're also continuing to play the game.
