I just read through an old parenting thread, which made me think of asking this question. In the thread, a childless user was told not having children made his opinion invalid. Recently, I stumbled upon a dog training blog where I found a similar comment.

I think the dogless and childless person made some good points, but in both cases, they were jumped on and, thus, silenced.

What do you say?

P.S. I didn’t put this in Meta because it’s not specifically about Fluther.
