well your original comment was about it being right, and I believe it isn’t.
this second post of yours is about why they would WANT to, and why it would “make sense”. Judaism doesn’t work that way. And that you would use the fact that it’s an identifier in the general population as a reason why it should “make sense” surprises me. I thought of you as someone who had a clearer picture than that. The fact that it’s “out there” has no bearing on who we ARE or how we view our places in this world. The fact that the world is using this painful reality some individuals live with as a way to hold their heads high is unfortunate, not something to join up with. and that whole end about feeling isolated from the frum community so it makes sense to join up with a group who encourage violating Torah itself? Please tell me you don’t mean that.
My sister had liver issues and was told by her doctor at age 18 that her liver could not support a pregnancy. She knew that she could not marry someone who was able to have children. It was beyond painful, but she didn’t isolate herself, she made a point of finding frum people who would be mechazeik her, who were older and single, who were married and childless, and who were married mothers of huge families. She did not align herself with secular groups fighting for zero population growth. She was not her liver. She was not childlesness. she was not single and childless but also frum. We may have many identifiers, but we don’t have many identities. Who we ARE is a piece of Hashem embodied in a physical body with all that comes along with it.
