Actually, you are wrong regarding microaggressions being a violation of your civil rights. Free speech by definition will produce microaggressions. But I do understand why they bother you. You know you are aggressive and look at your writings... nothing wrong with that in my book, but others would feel you are expressing microaggressions.
Perhaps because humans are aggressive, we need to put a fence around acceptable aggressive behavior and unacceptable aggressive behavior.
I think we agreed that there are racists in the world. Your definition appears different than mine. I define a racist as someone who intentionally aims to hurt others in some way, who are not part of their racial identity group. I define racism as the use of skin color/race in making decisions impacting a person.
If you are unpaid based on your gender and race, there are plenty of lawyers that will take your case. If a lawyer won't, they are telling you they don't think you have a good case. At my companies, we hired compensation experts to make sure we were not vulnerable to lawsuits for unfair pay ranging from who gets paid hourly vs salary, what constitutes overtime, racial and gender pay equity and almost any other criteria that someone has successfully sued a large company for.
If you work for a small company, they probably don't do that. I was underpaid for most of my career (mainly because I was always the youngest... VP, SVP, and eventually the youngest CEO). But it made it easy for me to leave, when a better job came along...
As an aside, I am guilty of overpaying people, I did not want to lose. They are called "golden handcuffs". Paying amazing employees 20% more than the market thinks they are worth based on their jobs title and duties, means often they have to take a pay cut to leave.
My oldest daughter feels like you do about her pay. I told her to look for a new job. If they don't offer her at least 10% more for changing jobs, then she probably is not overpaid, if they do, kick the dust off her sandals and move on to the next town. My rule of thumb was up or out every three years. I worked hard and if my company did not believe I was worth more, some other company would. It worked...
Note: most employers expect employees to stay at least 2 years unless an amazing opportunity comes along. After 2 years, you are like "free agent" and it may be time to trade.
