privately i am completely economically liberal and socially libertarian (e.g. free college and healthcare would be good if we could siphon the money off from the .01% and if you want to have sex with whoever, go ahead, that's your business) but as a science person i tend to keep my political opinions to myself in public contexts, like my online presence and public presentations (and even one-on-one i tend to try and feel out the other person before revealing my political leanings).

however, some scientists just go all-out with political statements. i find that inappropriate for the basic reason that if you want to be trusted scientifically, you shouldn't push opinions. of a scientist does that, people whose opinions disagree with that scientist will tend to think the scientist is untrustworthy in general and might distrust even their legitimate scientific results. in other words you dilute the power of your stances on factual science by mixing what you stand for with political opinions.

shit like pic related is just not good for science, as far as i can tell. people like that should just stfu and go back to the lab and do real work instead of meaningless crap like posing for lame political photo ops
