Weird places you worked in. Where I worked I could talk about anything I wanted and that's normal for every other office.

Actually that isn't normal at all. Have you worked in any companies larger than 10 people? There are legal liabilities employers have to (or are supposed to) uphold and more so for public companies. Starting with this: http://www.eeoc.gov/facts/fs-sex.html

Helps to be in a third world country. Sometimes I realize we have so much more freedom.

And yes, doesn't matter the company size. Ofc there are different situations but I always feel like people have a too broad definition of harassment.

Going a bit off topic, I know that's not the popular view in the western world, but I think you should fend for yourself in society and we are over reliant on rules and regulations, and then people complain about lacking freedom.

Dirty jokes are off limits if you want to avoid sexual harassment complaints.

If you don't have any choice in the people you work with and you can't find topics to discuss due to the strictness of conversational rules at your job, the problems at your workplace run far deeper than can be solved by going remote.
