But it's the actions that matter. The beliefs are irrelevant.
But I just brought to your attention that beliefs inform actions.
So you can't call the beliefs irrelevant if the actions matter.
If the actions matter, then the stuff that informs / motivates the actions matters also.
There is no question that human behavior has to be controlled. There is no question that we cannot control what people tihnk or choose to believe. So why on Earth are you so insistant on wasting time trying to control the latter? Why is anyone?
I don't think I said anything about wanting to engage in thought control, or even that such a thing is possible.
I just said that if actions matter, then so do beliefs.
This means that debate, discussion and education is worth it.
Sure, people are free to believe whatever they want. Other people are also free to try and change people's minds about whatever through discourse, debate, discussion, education, what-have-you.
And there is absolutely NOTHING you or anyone else can do about that.
Sure we can. Through discussion, discourse, debate, education,...
If you want to argue about something, argue about what behaviors support the well-being of your social collective, and what laws we should impose as a result.
I think you can not have that discussion without also talking about the causes of the behaviors.
