Teen moms VS older women

Does anyone else find it super shitty that when an older women can't get pregnant, she goes and puts teen moms down? I just heard a women say that "most teen moms, children, end up bad and not right mentally". And then I went to her profile and she's 30 and is having troubles TTC. why can't older women be happy for other pregnant women even if they're young? Is it jealousy? Because I think it's really fucking rude for someone to say my child more than likely will end up in a broken home because I'm 18 and pregnant. (Which is bullshit. My baby will have a GREAT life.)
