My (ex) friends having a problem with my kids being mixed?

This happened a few months ago and I just want to get others opinions on if I did something wrong.

I decided to become a solo parent by choice, my best friends were on board from the jump, speaking it into existence, buying me little things, sending me nursery ideas etc. over a course of two years because trying to conceive solo was a bit hard. At first I did at home insemination with no luck with a known donor (a friend of mine) but when that didn’t work I worked with a fertility clinic who only worked with one sperm bank. So, I was told to narrow down some donors they have. I did it based on the fact that they were a) ID Disclosure meaning when my kids are 18 they will be able to contact them B) Academics, Career, Family Medical History and how they answered the interview questions.

Somehow, my friends were very focused on the race! It bothered me because the donors I did end up settling on were all mixed race so I was confused but eventually I left it alone.

Fast forward this year, I found a known donor, I wanted this as an option as I didn’t want to keep paying $1,500 for a teeny tiny vial of sperm every time it failed. I decided to do at home insemination once more, I was ovulating based on OPKs and as I was on the way to the donor I texted my friends and asked them if he seemed like a good fit (I sent a photo of him with consent, his stats, academics, as well as genetic testing).

First thing my friend says is “why do you need an Asian baby?” I was appalled for a second because I didn’t even know how to answer that. I said what do you mean? And then it started to spiral into them attacking me saying all the people I wanted were Asian but I was confused because in reality I just wanted a baby and wanted a donor that was genetically compatible with me I didn’t care about what other race they were. This donor “happened” to be Asian, he lived within distance from me and was doing this for free! I told them there was a donor I did have in mind that was Swedish/German but his schedule never aligned with mine so we lost contact but they totally dismissed I ever said that. Looking back, the mixed donors had some part of Asian but it was definitely under like 25% but again in my head they were all candidates who had better family genetic history.

After my friends attacked me, It lead to a huge argument and I stopped talking to them.

I ended up pregnant by the Asian donor (first try!) and although on bad terms I told my friends. Then I told them that it was the donor they had a problem with. I then proceeded to ask, “will this become an issue? Like do you have a problem with this?” To which they said it was a problem. So then that’s when I ended the friendship and told them they don’t have to be in my kids life. I was a bit devastated as I just found out I was having a little blessing that they were excited for until they weren’t… they were my friends since middle school.

I was also confused because my other friends I talk to when I showed them donor options never talked about the race and never cared about things like that because they just wanted me to have a little bundle of joy and were excited for this journey with me. I just don’t know what I did wrong or if my friends were using this as an excuse to be mad at me?? Everything just hurts and I don’t know if I can forgive them because it’s one thing to feel some way about me but it feels like they would hold a grudge against my kids which I didn’t like.

Also one of the friends was in an interracial relationship!
