Yup! Bathroom bills are really bad for cis people too. The bills enforce conformity to gender stereotypes. A cis woman effectively isn't allowed to have super-short hair (even if she wants to look that way or is going through medical treatment). A cis man effectively isn't allowed to wear a skirt (even he wants to or it's part of his culture). And some people have hormonal variations/imbalances that don't necessarily "need" to be changed (says who?) and anyway can't be changed at the instant they have to use the bathroom. They shouldn't be reported to school/employment/police authorities to prove they're not trans.
