This would make the law depend on the content of the speech. I'd think that would make it subject to strict scrutiny for a potential first amendment violation.

This would make the law depend on the content of the speech. I'd think that would make it subject to strict scrutiny for a potential first amendment violation. There is a vague sort-of exception to 1A around "false statements of fact": https://en.wikipedia.org/wiki/United_States_free_speech_exceptions#False_statements_of_fact https://en.wikipedia.org/wiki/United_States_free_speech_exce... But even if that applies here, it would be constitutionally suspect to apply it to statements about just one particular topic.
