Groups self identify as Evangelical so by itself it is not a pejorative.
Neocon also is used in the US for Democrats that crossed the floor due to their difference in opinion with the party on foreign policy issues.
SJW is 100% pure pejorative.
It didn't always used to be pejorative. It used to have positive connotations but just like the labels 'progressive' and 'feminist', people like Argus started using it as an insult and it evolved to something bad.
There is nothing wrong with issues of social justice and those trying to belittle those values are the ones succeeding by devaluing the term.
That's why I refuse to be insulted by it.
I'm also a proud feminist and progressive.
