Meh. I don't have pets and so I don't know why not getting your pets spayed is irresponsible.
But just about the conversations you had on the forums, I suggest you either ignore them or come up with a good retaliation or just quit. Those people who are inconsiderate of others' emotions and expressions are clearly not worth your time. Considering you are at a pretty young age, it's natural for you to make mistakes; everyone makes mistakes and that's how people learn from them. All they're doing is just attacking you for some mistake that you made. Sure you're only 10, but that doesn't mean that they need to go to great length to attack you like that. Unless of course, they, unlike most people, have no emotions at all. How would they feel if they were in the same position as you? I suppose they really can't be a little more considerate. Just look at how different the responses are in here than there.
On a happier note, your dogs are majorly cute!

I've always wanted a pet (I like kitties ^w^) but my mum doesn't allow it ¬¬
