What to do about someone pushing lgbt stories at work

An employee making me very uncomfortable at my job at Walmart. I've got an employee who works on my team who is married to a man and a woman. He likes to crawl stress and everything was telling me about it, and I was just trying to keep the peace cause I'm afraid in this day and age you getting fired for disagreeing with liberalism Well today he was showing everybody pictures of himself and his new dress that his husband bought him and at this point, I think it's being shoved in my face and I don't know how I'm supposed to handle it without possibly losing my job. I know we're supposed to stand up for Christ but in reality if I lose this job, it's one step between me and homelessness. I'm one of these people that I'm never one paycheck away from being filled out. I barely make it payday to payday. I really don't know what to do.
