There's not really a unified "anti-trans movement", as different people have different reasons for opposing this.
Like for instance you mention homophobia:
> that the previous anti movement (homophobia) has effectively failed
But one of these reasons for rejecting the ideology of "trans" is because it's homophobic.
Consider the conventional understanding of homosexuality: a sexual orientation directed exclusively towards others of the same sex. The "trans" belief system overwrites this definition to instead be those who are attracted only to others with the same "gender identity".
This means that a "trans woman" (male sex) who is only interested in "cis women" (female sex) would be a lesbian by this new definition - which effectively erases homosexuality in its original understanding, by including heterosexuals. In this case straight males.
In the past few years, LGB organizations have been springing up to counter this new type of homophobia. Often driven by or allying with feminists, who have their own set of reasons to be critical of "trans".
