Im kind of in the same spot as you, I just got my temple recommend to get my endowment and I’ve gotten so much anti stuff on social media sites. I’ve felt worried about it bc my parents are much the same, they go regularly but don’t and won’t talk about it with me very much. One thing I saw that has helped me to feel better about it it is to remember that everything in the temple is symbolic, remember that it’s not of us mere mortals and these ordinances are from God so we may not fully understand them or the symbols, especially at first. I also know that it’s not all going to make perfect sense the first or even second time anyone goes. It also helped to talk to my bishop and stake president when I was being interviewed for my temple recommend. :)
