LJ is full of relatively sane people, and I will make my home here forever. Tumblr is a scary place if you wander around too far, but you can usually make a nice little corner for yourself, if you build a good security system and an bunker for emergency purposes. It's just never a good idea to walk around in any tag of any sort. There will always be someone there spreading hate about the thing you like that will either make you irrationally angry, or ashamed for liking it in the first place.

LJ is a much kinder place.
