I don't think conventional minded people think there can't be things that you can't say that are true. I think they believe that you'd be aware of the things that would get you in trouble, and that those things were already explored and collectively rejected by society (or most of it), and there is no point in you pushing it with "...but I really do want to say it". They know some people think those things and they're fine with it. They're not fine with you chanting it. Basically, get your group if like minded people and talk about it in your closed walls. Especially the things that are or might be true, it's important to understand that: - They might be harmful to others, true or not - Others may need to be harmed in order for society to find if some of those are true, but you might already have figured out that they are - Those true things might be an obstacle for society to remain stable and cohesive - Maybe those true things can bring some progress, but they might not be worth the cost All in all, I think society has a mechanism to self censor and some are ok with it, some aren't. I however do not agree that unencumbered freedom of speech will lead to a better society. But yes, I do think some taboos today are excessive.
