The tone of Christian Gym Goer is teetering on incel. He doesn't take responsibility, he pushes that on to the "immodest women" who "don't follow the dress code".
If the mere presence of women in non-restrictive clothing causes Christian Gym Man to have to immediately pack up and exit the vicinity, that's really weird. This man need to learn some executive function, not complain about immodest women.
Also, the whole "so much for the tolerant left!" argument is so trite and weak. Intolerance OF intolerance is 100% necessary, and not equal on either side of the isle. The Christian intolerance of "I want to enforce women to a dress code because I can't control my sexual urges" is worse than "you shouldnt do that".
