I voted other because it's honestly been a really long time since I went online with the direct intention of getting into an argument. I pretty much only had the energy for that when I was a lot younger. It carried on for quite a while because I was used to it and it was hard to stop and let things go.
Anyway, yes. I've done it (as some here well know). I'm not sure if I think it was healthy or not. Probably wasn't good for the other people. I try not to now because arguing makes me tired and makes me feel like crap. I occasionally do the political thing but generally don't do it on SAS. I'm just not as passionate about anything as I used to be.
In case of emergency, my husk can be used as a flotation device.
