The point I'm making is that there are lines to be crossed and if you don't understand that you have simply taken a hard stance on some aspect of this.
That all being said, YES I totally agree the dev should have full rights to say that in his software - but we can have an opinion too.
To use a hypothetical example - a cereal company puts some tasteless comment in an unobtrusive corner of the box. You don't have to look at it if you don't want to - you can turn the box, or put the cereal into another container, or just not read the box that closely. But why would you want to when there are 45 other brands of cereal on the supermarket shelf?
Conversation is pointless as OP has now responded saying he simply doesn't like hearing about sex.
