TLDR The left wins when we achieve working class solidarity. Excluding groups of people based on identity isn't solidarity.
At first I thought that I needed to know what your argument defined as the left to respond to your argument. Then I realized my argument is the same regardless of that.
Any movement that success depends on excluding trans people or Palestinians or any minority group for that matter is not one I want to be a part of or one that I have any interest in succeeding.
If all we are willing to fight for is success for a handful of white cis straight men of European decent then we've successful divided ourselves so thoroughly that we are doomed to be ruled by either Republican fascists or Democrat fascists who serve the owner class.
Bigots use biology as a crutch to justify their bigotry. That's how I know this woman is a bigot. Unless we are all willing to work together to fight for each other's rights we won't get anywhere. That means voting Democrat for the most progressives candidates we can in elections. It means solidarity with groups the Democrats would rather abandon between elections. It means abandoning bigotry and sticking with trans people.
I'll phrase it another way. I support lesbians. I am a lesbian. Why doesn't this woman who supports lesbians support me a transbian? How is her subscription to a division in the working class that benefits the owner class not the debilitating issue in this dynamic? Why is she not the reason the left is losing?
Why is my desire for rights the issue when I support her rights and the rights she is fighting for? I knew nothing about this woman before seeing this post. I still know mostly nothing about her. I know she doesn't support my rights though. How am I supposed to have solidarity with her when she already went out of her way to exclude me? And why am I being gaslight into thinking I'm the problem?
There's an idea that says we should abandon certain people based on the likelihood embracing them will cause a movement to succeed or fail. It of course adjusts this calculus based on preexisting notions of what is normal for race, ethnicity, gender, sex, attraction, physical appearance, personal ability, and everything else that shouldn't matter at any given time.
The refutation of this line of thinking is straightforward. If we abandon trans people today it's lesbians who will be abandoned tomorrow. But more to the point, this line of reasoning completely undermines the premise it pretends to stand for. To reiterate, the argument says, "We should stop caring about X group and just focus on the working class and calling terfs bigots is the problem". But X group is part of the working class (X was gay people in a comment I saw elsewhere that seems to be an emotional appeal to rebrand neoliberal shifting to the right as socialist). Trans people are part of the working class. The only group that isn't part of the working class is the owner class.
Refusing to care about a certain group of people isn't working class solidarity. It's doing the work of dividing the working class for the owner class.
Y’all are why the left is losing.
If you want to know why the left is losing look no further than your comment. I'm not going back in the closet. I'm not giving up on my rights because it will make it convenient for you. Fuck terfs. If she wants my support all she has to do is put down her bigotry. I'm still standing in the middle ground where lesbians and trans people get to exist thanks.
