The Internet is largely public. If you post in a public place, and are linked and mocked in another place, then it perfectly within the rights of the linker to mock you.
Its not their right to harass you, threaten you, or send a slew of trolls to your own website, but if the matter consists solely of linking and mocking, its hardly "really low" or "messed up."
If you get linked to on When Fangirls Attack, and then linked on another blog and mocked, the linking and mocking is not "the lowest of the low." Yes, sending trolls is low. Yes, some insults are stupid. However, a lot of different opinions are linked on WFA and it is read by people from various sides of the political spectrum. Linking and mocking will occur.
Bear in mind that the vast majority of the blogosphere is people linking other people, often for mockery. And if you were linked and mocked for linking and mocking someone's interview or point of view, they're pretty much doing the same to you as you did to them and it makes you particularly annoying and silly to the neutral onlooker. That's the Blogosphere. Its the wild.
Defend yourself, by all means. Ignore them, by all means. Express your personal opinions about their parentage, by all means. If you get trolled, lock down you blog if you must. If you get threatened, Complain if their mocking specifically called for people to troll you. Argue back, retreat, whatever you must. But don't make generalizations about "Bloggers" (Especially if you are one, and if you have a livejournal, you are one too. Deal with it) and don't make bitter statements about them linking public posts.
I say this without naming names or linking what brought this about because I've seen more than enough complaints over people being linked and I'm downright sick of people posting in a public place and then complaining they were linked in an unfavorable manner. (Or, in the case of one fucking idiot, a completely neutral manner.) You think I haven't been called crazy, or creepy, or stupid, or had a post fisked?
Guess what, that's their right to do (even if they are wrong) and I do the same damned thing on this blog all the time. If I'm not being threatened or trolled, who the fuck cares if they make fun of me in their own private part of the internet? I have mine to mock them from.
Lock it up if you don't want anyone who disagrees reading.
