What you say on LJ is a reflection of you, and you should expect to be held as accountable for it as if you posted it on a bulletin board at town hall, or spoke it at your dinner party.
Dismissing criticisms of your actions as “It’s just LJ” or “OMFG DRAMA!!11” is demeaning to yourself, and to the people who care about you. There’s no such thing as ‘just LJ’ or ‘real-life’ — You may not think about it, but when you’re on a computer, you’re still living your very personal, very real life. It’s not made any less ‘real’ by virtue of the fact that there are protocols and transistors and light-speed communications involved.
Everything you say, everything you do, every friend and enemy you make is a reflection of your character, morality, and ethical structure. Of course, everyone is free to do as they wish with their own journal, but they shouldn’t expect it to exist in a vacuum, without social and personal effects and repercussions. The defense that ‘no one is forcing you to read it’ is as irrelevant as it is in regards to racial/sexual/religious intolerance and hatred. If you don’t want it read, don’t make it public. If you don’t want to be held accountable for it, then don’t say it to the world.
If you find this concept uncomfortable, then perhaps you shouldn’t spend your time posting to a community site with over a million members on it.
If you don’t think or care about what you’re saying online, why should anyone expect anything more from you in the ‘real world’?
That is all.
