Well today in "tech", if you openly support a republican candidate, good luck being invited at tech events or conferences as a speaker.

That's wrong of course and I say that as a non republican. The Tech industry has become so politicized positions that used to be seen as extreme are considered "normal". I mean how can an article such as this one can be deemed acceptable on a tech blog ? : https://archive.is/elvvc

Replace white people by black people and racism, defined as broad generalizations based on the color of skin, becomes obvious. Yes the article linked is racist period.
