These are rather tame words, they are only offensive to those who decide they feel offended by them.
Honestly, the whole concept of banning swearwords is already childish at best. I get why it's done, but there isn't much of an actual point to it. However, getting rid of words like gay or sex achieves absolutely nothing, really, unless you are a prepubescent kid shocked by the simple concept of sex due to your fear of sex more than anything else... we all go through that during the preteen years, it's normal
