Now before you freak out about the another or call me out for being transpose. Know that I am poly and in a relationship currently with my girlfriend who I love very much. We have been looking for more partners recently and on a dating app I matched with a girl who was pretty cute and we barely talked when I asked. The reason being is I want to start having kids and want to look for partners who well for a lack of a better term have kids. Now I know adoption and egg donor/birth donor is a thing but it's ridiculously expensive plus a lot of issues with that. Now we had only begane talking for two days and when she said she was Trans I said I didn't want to keep pursuing the romantic path but we can be friends I just didn't want to lead on. Well I was called out for being Trans phobic and was banned from the dating app. I just want to know if I was in the wrong because my partner says no but I want a more not so biased opinion

Update

Thank you so much for your opinions they are very helpful. I do want to clarify things because there was a bit of misunderstanding, though that was my bad for not writing better. I am not looking for a new partner just for her to get pregnant. That would be horrible and disgusting. The end game is to start a family, and unfortunately, I can't build that with a Trans girl, so that's why I don't want to build a relationship with them because that doesn't fit the end goal. With the other partner situation, we have discussed finding a new partner for a while now almost a year, and we have had a few flings, but we recently decided to bring someone in for hopefully a permanent and we discussed what our long term goals were and having a family was one of them.
