Don't tell them. I don't want to have to enter 30 characters. And it does not help for the people you'd need it for anyway.

No, just longer to type. You can't fix stupid people by making the life of non-stupid people worse.
All you do is for non-stupid people to stop caring and do the easiest thing possible too.
I would hate to be labeled 'stupid' everytime I don't want to type some 30 dumb characters everytime I login. How about no?
Different difference ;)
I also don't want to type 30 chars, when 15 _properly randomly chosen_ characters would suffice but the "stupid people" chose those 15 characters as "passwordP@55w0rd" and now everyone requires us to write 30 instead because it's "so much more secure" when they write "passwordP@55w0rdpasswordP@55w0rd"
That's why we recommend passphrases. That 30 character requirement becomes much easier when it's 3-4 words with a separater. Faster to type, too.
