I don't think it matters if 'points' is all she won, but it matters when people are getting upset and feeling put down.
I've occasionally seen people make claims where I can tell, and anyone who knew the topic well could tell, that they are at best rather exaggerating what they know, and at worst making stuff up. And that's fine, so long as it's not a topic where someone is invested in it, or where someone is actually taking serious advice.
I know we all know you can't trust people on the net, but trolls/liars prey on the people who are a bit new to all this or who've got sucked in, don't they?
It's the double standard for 'remembering' that I find difficult. I commented on something a while back and got a right slap down from someone who said that 'in so-and-so's circumstances' I should be more sensitive. And I felt a right twit, as I should have done, because I didn't know her circumstances and they were awful, and if I'd known I wouldn't have posted as I did.
So quite obviously, most people do remember stuff.
It is better to stick to what the OP is saying and leave it at that, generally, but there's always a few exceptions.
