Family's reaction to our adoption

If you know my family you know they are very pro adoption, they believe in helping these kids and they love the idea. Several of my siblings and nieces and nephews were all adopted so it's not like this is a new concept for them. However, none of them have been fostered to adopt, they were mostly out of country adoption or a "sibling" adoption. This was our first time dealing with the foster care system and the first time we had a sibling group this large adopted all at once needless to say my siblings and my parents all had something to say about it. My dad straight up told us we were crazy, that we didn't know what we were getting ourselves into then he added "I support whatever you do, but please make sure you pray about this." My sisters, let me just say despite the fact there are over 20 little kids in the family they act like they have never seen a baby, so they were excited. They have an adoption shower planned, they have all these things they want to buy the kids-they're pumped. My grandpa however has expressed his feelings of not supporting this multiple times. He believes that me being gay is one of the worst things that could possibly happen to the family and to raise kids would be an abomination in his mind. He has told my dad so many times that he can't support this and won't stand by and watch me adopt four kids and "turn their lives into Hell" he felt so strongly about this that he skipped my wedding reception we recently had and packed up all my pictures. Yea. He's mad, but despite one family member feeling that this is wrong I know what I want in my heart. I don't talk about my job much on social media, but I work with orphans in one of the poorest countries in the world, I've seen first hand what happens when kids have nothing and I want to make sure I do my part not just away at work but at home as well to make a difference. My sister, Jess(you guys know her right?), and I were watching The Blind Side and a quote stuck out to me and I think it's super fitting right now "You're changing that boy's life" "No. He's changing mine.". No matter who disagrees with us, I will keep that quote in my mind. My kids have changed my life for the better and I'm so utterly thankful and I'm thankful for all of you reading this who are supporting us as well. Thank you from the bottom of my heart.
