I don't think the issue is around forced conversion therapy or associated practices, but this notion of whether someone can consent to what is inherently a fraudulent practice, such as conversion therapy. There isn't scientific evidence that supports its efficacy to change someone's sexual orientation or gender identity. How do you consent to something that is unscientific and that is based in an anti-LGBTQ ideology? That's why many people want the inclusion of adults. The notion of “consenting adults” is just a complete misnomer.
Likewise, let me say briefly, the problem with the legislation is that it says that in some cases conversion therapy is not acceptable for minors, but in other cases it can be acceptable for adults. It really sends a mixed message about the harms and dangers of conversion therapy by creating these artificial distinctions based on age.
