I don't know if SJWs themselves "created" Trump. However, I do think years (if not decades) of the Left elite ignoring working class America and the big ways in which the DNC screwed up in this election had a part in it.
The 'SJW' left hold the white working class pretty much in contempt. They will bend over backwards to excuse intolerance, as long as it is intolerance performed by a 'persecuted' group. The only group not allowed to have an identity is the white working class.
They also lack any sense of scale and cry wolf too frequently. When someone who mere lacks understanding of the finer points of liberal PC etiquette is labelled as racist, this makes it much harder to call out the
actual racists and bigots.
This is more the icing on the cake than the substance behind the rise of Trump and the right though.
The main problem is that reality has caught up with ideology. The ideology of liberal globalisation has failed large sectors of society and you can't keep telling people things that don't match the reality in which they are living.
The disconnect between the working class voters and cosmopolitan liberals has been growing for a long time.
While the elite tends to support and benefit from globalisation and multiculturalism, the social harms are borne by the working class. People who can afford to isolate themselves from the problems use the issues to signal how virtuous and tolerant they are, then compound this by labelling as 'racist' and ignorant anybody who thinks differently.
This is really more of a centre-left/centre-right issue than a purely partisan one. Their ideologies lost the war with reality, and as of yet they don't seem to have accepted this fact. Blaming fake news, FBI directors and Russian hackers is a comfort blanket, but isn't going to make them more electable.
They have subscribed to the myth that ultimately all educated and reasonable people should agree with their values. Those who disagree must therefore be stupid or unreasonable.
What is truly unreasonable though is their myth of inevitable liberal progress towards a society comprised of people exactly like themselves.
