I'll admit that it's stuff I've seen more on Tumblr (where, for the past decade, there is somehow a "debate" on what can cause plurality) and I hear it's also a thing on TikTok.
In all fairness, collectively we don't consider ourselves trans beyond a political solidarity sense, though that's because our body is also intersex than anything to do with our plurality, we consider ourselves collectively ultergender. Though the experiences section doesn't have our experience, which is "our visibly intersex body is fine the way it is, and we refuse to binarize it".
That being said, some of us do consider themself trans, a few of us consider themself cis, and some of us consider themselves ultergender or ipsogender.
