I will not take it personally as it is, sadly, a reality that I've seen also. Something I try to avoid as much as possible also. If someone does not like PvP they should not taunt others because they think they are safe. But unfortunately, this is not a perfect world. If I meet someone like that, I just walk away if possible.
in the end, as long as the pvp rules are clear, then everyone should be able to play by them.
Perhaps players can have an agreement between themselves that they want to pvp with each other but will leave others that do not want to alone? Might get complicated...
Sorry, I always try my best to find a middle ground in things
