I have wiggle room on a lot of issues, human rights aren't one of them, it can't be one of them.
Is it a right to play sports?
We live in the United States of America, everything legal is a right. The stance of "it's just sports" is a real easy take for someone who doesn't have a whole lot of people trying to take that away from you. In fact, as a cis white male, I don't believe you have anything to worry about, I'm not aware of a single bill, anywhere in the country, trying to restrict you from anything. Literally every single person participating in this conversation, other than possibly dax, also knows that this prohibition on sports isn't an end point. In Iowa alone, this year, there have been 29 different proposed bills that place some sort of limitation on people who identify as LGBTQ.
Is this similar to how everyone knows that "common sense" gun regulations aren't an end point?
I have no idea, maybe? I can tell you that there isn't a state in the country with 29 current bill proposals that restrict gun ownership. When that happens to gun owners, let's have a chat. When we do have that chat, I'll make the very common sense argument that guns aren't people.
Is 29 the magic number? There are lots of bills proposed in states and passed in states that restrict gun ownership in the face of clear Supreme Court decisions.
I don't know what the "magic number" is for you. I can tell you that when it comes to me and civil rights, the magic number is 1. I'm not going to compare gun rights to civil rights, that's not something I would ever do. I am human enough to not compare bills about limiting metal and gunpowder to those about limiting actual people, in the flesh, that have feelings, emotions, who bleed, and have a finite time on this earth.
