Why do we rip apart woman once they get BFP?

I don't understand a few of you ladies on here. This is a supportive community, but as soon as someone has a question about babies or wants to share their good news with the woman who have supported them through months or years of trying, YOU choose to go on the post and steal their joy. It's shameful and sad. If you don't wish to read something-look at the topic title! You make the choice to look which then upsets you. Personally, I don't go on the success stories page, it makes me sad. But if I woman who is excited wants to post and let the people who helped her along the way know; I see no issue with this. If a woman TTC is posting a question about anything to do with baby things, she shouldn't get mean remarks. She is TTC and asking other people who are TTC but are also mothers.
