But what about the many users who are not parents?
To call it parentsnet is excluding them. By your argument, that is.
So it would have to be PeopleNet in order to reflect the users. Or MumDadGrandparentAuntieUncleFriendTTCTeacherCMAnyoneNet.
Do you think that by calling it 'parentsnet' - it will change anything?
Do you think that anybody with half a brain thinks oh, it's called Mumsnet - clearly if you're not a mum you don't go there. Oh, now it's called ParentNet, I'll join now.
I mean, you can think what you like, obviously. That's your view and you're entitled to it.
Reality is - the name is mumsnet, the users are people who are mums, or dads, or grandparents, or uncles, or aunts, or childminders, or nannies, or teachers, or business people... and anyone who wants to use it does so.
And the name isn't going to change. The owners of the site would have to be bonkers to spend ten years building up a brand and then change the name because a few people think that the word 'mum' should be removed.
