To be slightly more (maybe less) fair from an admittedly leftist bias, I think that the example of age verification misses another important component that has been pulled into the culture wars: a lot of age verification laws also target things like sexual education, which in some cases is construed to mean anything that touches on queer identities, even biographies and basic educational material.

The religious right tends to be against all forms of sexual education that aren't based around abstinence and usually want explicit parental involvement, but many on the left feel a basic but complete sexual education is important to educate kids about consent and bodily autonomy, which often helps children recognize things like grooming and assault where other forms of education fail.

Unfortunately that is an emotional topic and quickly gets into an area where classic libertarians (and there doesn't seem to be many left, these days) prioritize parental choice over freedom of speech. The EFF still needs to navigate these issues to be effective, but I don't think the old coalition holds like it used to.
