It's impossible to take this author and article seriously when he opens by describing "justice for women as well as for lesbian, gay, bisexual, transgender, queer, intersex, asexual and allied people" as being "politically lopsided".
The author whines about progressive events existing without conservative events. He never describes what sort of conservative events he would want to see.
It does seem ridiculous. Devil's advocate, it may be that he is so immersed in campus culture that he assumes everyone knows that "justice" is code for illiberal leftist ideas like the progressive stack and forced equity.
