I said might. Even Nobel Lauraetes are being fired for saying the wrong thing and there is a clear implication that you shouldn't take a classical liberalism position such as 'the most qualified person should get the job'.
There are two main things you are overlooking here:
1. Intent. There is a tendency for some of the people pushing this agenda to project intent even if there is no intent; for example: men's rights groups are secretly evil misogynistic hate groups so we need to ban then at U of Toronto and Ryerson U. The etymology of 'microaggressions' implies aggression thus intent; micro-offenses would have made more sense. We even see it in this thread with people like Blackdog and Cybercoma trying to project some hidden intent onto me.
2. Equitable Application: I see no reason to believe there will be equitable application of these microaggression policies and a lot of reason to believe otherwise. Somehow #killallmen, constantly telling men to 'grow balls' and 'man up', dismissing male issues while drinking out of coffee mugs that read 'I bathe in male tears', telling men that they are inherently evil rapists so need to take classes to learn how not to rape, not taking male rape victims seriously, constantly telling men that they are 'privileged' for being men while women have higher life expectancy, higher self-reported happiness, lower suicide rate, lower rate of being murdered and assaulted and outperform men academically due to a combination of higher emotional support for women, constant pushes and programs to get women ahead academically which are absent for men, and educational practices which are optimized for women/girls while men/boys are put on Ritalin, etc. aren't microaggressions. And then people wonder why male suicide is so high.
