So sorry you had to go through that, or that anyone should be discriminated against at all. Regardless of GID, gender, race, religion, etc. We have a long ways to go as a society and species sadly when stuff like this still happens.
That being said, I'm glad you're ok. And I agree, everyone should take self defense courses of any sort. Focus on what your stronger features are, do some research, and find a fighting style/martial art that uses those features. I have thick strong legs, but not very strong upper body, so I'm looking at Muay Thai kickboxing and Jeet Kun Do (specifically for the mentality of "Take what works, eliminate what doesn't, make it your own" on top of it being the style Bruce Lee brought to the rest of the world).
