Because is that what it seems to be...?
Like I usually see the term "SJW" being used even on the most obvious cases of prejudice against a minority - be either, trans rights, blantat misoginy towards woman [i.g a woman expressing her sexuality = asking to be called a ***re], religious discrimination, racism etc] thus ignoring the issue beforehand even if facts are given.
People who don't even act
remotely like the so called 'tumblr'-stereotype [which I also have yet to see within the site itself] of pre-teens that go on saying people should kill themselves and other isults, are labeled as one [also why caring about an social issue = bad thing???].
