I’ve lived both lives and I strongly believe that the garbage is hurled equally from/to both sides. Nasty and intolerant and closed minded. We have posters who come here telling off the “black hatters” for their closed minded attitudes, while adding that they expected no less from them. And they don’t even hear their own words.
I personally think a major difference is that people view the “black hatters” as self proclaimed holier people so their infarctions are considered hypocrisy in addition to bad middos.
