it's too easy to be an asshole online, i know i've been doing it on and off for 25 years. nowadays a bit less, but that might just be because im old and lack the energy.
i remember having constant arguments about the stupidest shit with real-friends on IRC, about veganism and music and shit, and things would often escalate way too much, when in real life we all got along just fine. i loved to chill with them, and would always try to be nice company, and they were cool to me too. but online.. totally different. i thought about it a lot and i think ultimately for me it comes down to online being too detached, you dont see other people's smiles or frowns, hear their intonation, read their body language.. it just lacks 90% of whats important to me in person-to-person interaction, and i just could never take online seriously as a result, i just said whatever came to mind and i guess assumed no one would take me that seriously because i didnt take them seriously either, i mean i couldnt even see or hear them!
this might just be me though. i simply find it rather impossible to think of online chatter as also part of reality, and that it can have consequences. i never even cared about some threats of violence i got from neonazis lol (many many years ago), it was just online comments so who cares right?
i dunno, i wish the internet got destroyed and we all just lived face to face again. this shit's depressing.
