Edit: and something to add, that is a negative situation because allowing you to block these people completely over this addition is perpetuating an option that allows segregation over feelings that are completely irrational. Allowing you to block them justifies these ridiculous feelings.
No, because I'm not preventing you from enjoying your jumping. I'm not preventing you from doing something out of boredom. You want to whine about segregation? You're the one that wants to force your enjoyment onto me. Allowing one or another to block people allows both sides to enjoy the game. There is no rationality in preventing someone that doesn't enjoy the game as you enjoy it from enjoying the game the way they want to enjoy it, using the same logic as people that want jumping to be put into the game to begin with.
