what's your point? I don't think intent comes into play at all, and obviously opinions, concepts will not appeal to anyone.
There is no universally acceptable ideal. Some people long for a simpler time when people lived off the land, some people wish technology could get to the point where they could replace their own bodies.
The merits of a free society is that everyone can pursue their own happiness, which will always mean different things to anyone.
I plan to vote in my own interests, and I know someone who has entirely opposite ideas than me will vote in their own interests.
Like I said before, no matter how dishonest or exclusionary someone's opinion is, it's not something to be hidden from others for fear that they'll be "corrupted" by this toxic, memetic idea. You have the power to provide a counterpoint, and the ability to convincingly debate and discredit is what is important, rather than "remove" or hide an opinion.
Just look at InfoWars, they're super popular and they've enjoyed a boost lately because I believe CNN lobbied to try and make facebook delete all their content so no one could see it.
That behavior feeds right into the mentality you want to remove. Only through counterpoints can you dispel nontruths, any idea that is seen as "too dangerous" to be given exposure will be seen as a powerful idea, and indeed that is the case. Ideas are inherently dangerous because they are powerful - and only more powerful truths can dispel them. Not doing so seems to imply you cannot fight them on an even ground. This is literally every opposition's tactic and it always works.
