What are they afraid of ? What bullying ? What harassement ? Just because someone doesn't like others actions ?
The same argument you made "cause and effect" seems like it was what created this post in the first place.
He just said he was going to the event no matter how confrontational it would be, he didn't say he was going to harm anyone.

Thousands of years ago they'd banish someone like you from the tribe for being the way you are. And if you continuously showed up just to harass everyone like you do here, those folks wouldn't be downvoting you. They'd be shoving a spear up your ass and rotating.

Why should I sit back and allow you walk all over me? Expect people to just sit back and take it up the ass? You expect people to be complacent while you sit there tormenting them?

This seems more like a threat or raging than whatever he mentioned above and I doubt anyone is going to take any real life actions against you.
Glad we are evolving as a civilization. Shame some are so tormented.
BTW, the biggest downvoters are not "people".
