How can an entire discipline that is supposedly based on rational evidence-finding be such a cliquey clusterfuck? You're basically saying that if you don't follow the community rules, which more or less boil down to "hazing," you'll be excommunicated. Sounds like a cult, to me... as is any culture where "fear" is the primary motivator not to try something different.
Don't the laws of nature exist everywhere? Why can't anyone "do science," then?
I am glad I work in a meritocracy-based industry where anyone with any background can "ship" and succeed, and that has a low tolerance for bullshit.
