I've heard the same said about r/the_donald etc. That argument falls flat when an overarching theme is a reality. Terrible people always try and lump themselves in with the truly innocent who are oppressed to engender sympathy as victims. There are increasingly common intersections where a duck is a duck.
I agree and its disheartening to see the amount of responses in opposition. There is a massive number of comments on this post compared to most social topics, or ANY topic for that matter, and a lot of them are arguing it's wrong or bad to have limits on such behavior. I would suspect many of those arguments are defensive in origin and disingenuous. But for those who aren't personally involved in those behaviors, who opposed limits and rules, I don't know how they imagine a total free for all could work. We need government, structure, rules for society to exist. Otherwise as has been shown when limits are removed, the worst people and of people will ruin it for everyone else. If you could count on people NOT to be terrible it would make all of this a lot easier. You cannot.
kg x2 + 10% = lbs
lbs /2 - 10% = kg
I've yet to find a fast one for C to F temp conversions though. It takes a bit longer to do the 9/5-5/9 + or - equation in your head.
