A
person on the fringes of authoritarian left-wingdom, who is really too
stupid and/or
gullible to be taken seriously. They often utilise emotional outbursts (otherwise known as 'tantrums') instead of actual reasoned debate and critical thinking.
This frigging leftoid just denied the validity of scientific research on genetic differences among populations after watching a
far-left YouTube video. I've nothing against free-speech, but this motherfucking
anti-freedom leftoid screed has colonized the discourse space of a seminally good
idea.
