I haven't seen the video. Sound awful and I think many people like me won't even click on it (to not add views), so the ratio of likes might be skewed because of that.
Having said that, I think people who are in favor of conversion therapy should have parental rights removed. Conversion therapy is torture. Any parent who can imagine one situation where torturing their own children is acceptable, should have parental rights removed because they can't be good parents. You can't be a good parent and torture your children.
And let's face it, if you would torture your child for not liking who they are, then what prevents you from hurting them for other reasons?
If the OMS has already classified conversion therapy as torture. In my country it is banned. But if in your country is not specifically banned, those who participate in that, should be reported for promoting torture. Isn't that illegal?
