If they wanted to look at replacing or modifying or even jjsut do some analysis of the effects of this kind of legislation, I think I would support that.
I've overall become much more reticent about the effects of equal rights types of bills, I think they do not always work as one might have hoped. Sometimes they don't really add anything new, but also they can have what seem like perverse effects, or be used by those with evil purposes.
But going off half cocked is never good. You need to have a good idea of what to expect as a result of your action.
I am curious who something like this is appealing to. I don't think there are many people who want to see women fired due to pregnancy, or people not hired due to race, or anything along those lines. Where it appeals, I suspect it is because people are seeing things happen that seem unfair - maybe things like accommodations for workers that hit others negatively?
It's worth understanding where people are seeing problems, I think, and it's not just about trans stuff.
