Also have you ever seen someone arrested just for wearing a clown costume.
Nope, but that might be because 17a (3) says it does not apply to common public festivals, which Carnival certainly belongs. Also, there is no general ban on masks in public. Only at gatherings.
IMHO Debian and Ubuntu should be swapped: swapped:
Debian as the serious guy, that’s doing the hard work under the hood while the flashy Ubuntu gets the credit for being popular.
