If they're voicing it strongly and expecting that I'll agree, then yes. I mostly do that in person, though. I find that getting pulled into arguments online is a massive time suck, and it's rare that anyone changes their mind. So if I see an opinion I disagree with, I just post my own or support others in the thread that accurately voice my opinion as well.
apsolutely, the more someone is rude the more I wanna kill him with kind energy and practaical solid argument but sometimes I feel like it's waste of my time and when I'm too attacked I feel it's bad for me cause I can get really upset
I do when I feel like its an attack on me, like if someone says "it's your fault that you've been at work all day" when I was at work because all the faxes were broken and I had to fix them when my job is actually just to fax things over, and it couldnt be done without a working fax machine. I crush that.
No 99 times out of a 100 I think the argument would turn into me posting 20 comments saying black and the other person posting 20 comments saying white with each person still holding same view at the end - I just say cut to the chase and agree to disagree.
