Thanks, Peter. :) I agree about appearing normal when the issue is trivial. I'm not convince about minimizing weirdness on important topics. Some counter-considerations:

• People like Nick Bostrom seem to acquire prestige by taking on many controversial ideas at once. If Bostrom's only schtick were anthropic bias, he probably wouldn't have reached FP's top 100 thinkers.
• Focusing on only one controversial issue may make you appear single-minded, like "Oh, that guy only cares about X and can't see that Y and Z are also important topics."
• If you advocate many things, people can choose the one they agree with most or find easiest to do.
