SJWs are completely unrelated to scientists. It is pure coincidence that many scientists are liberal, but that has more to do with conservatives' ignorance of science and suppression of science (e.g. under Stephen Harper conservative government, nearly one-quarter of publicly funded scientists reported being directly asked to exclude or alter information for nonscientific reasons). Scientists are often on the opposite side of debates than SJWs (e.g. one group of scientists went so far as to troll an SJW journal called Social Text by publishing a parody paper claiming gravity was a "social context").
