But removing someone is on par with a personal attack.

No, it's on par with letting the GM's run their own RPs. A player does [b]not[/b] have the right to play in a particular RP, and enforcing that is just going to cause the departure of GMs. 

If a GM doesn't want you in an RP, you shouldn't be there. It's not instantly a personal attack, maybe you're just not a good fit. Maybe your character is incompatible, or you simply didn't write with people (loner in the bar scenario). Maybe you fell off the activity horse long ago and the story moved on. Maybe the game has a limited cast and had to replace you. The list goes on and on. 

Yes, there are personal attacks, but those are the exception, not the rule. This is about GM sovereignty, not autonomy. A very subtle, yet critical, distinction.
