Especially since when you're online, you have so much information at your disposal. It's impossible to convince anyone. Because they can bring a random article saying "Orange Man Bad", which then you can immediately respond with an article about "Xi Biden Bad". And at the end of it, no one is convinced of anything, because you effectively allowed other people to debate for you by using their words and ideas in place of your own. In person, you don't have the ability to pull propaganda out of your ass on demand. That's why the first debate was a shit show but Kamala got decimated in the VP debate and so did Biden in the second. Searches to change your vote by earlier voters who already voted for Biden spiked after the second debate.

Debating in person where you actually have to know what you're talking about and word your argument convincingly, is a world of difference from online.
