Have you ever just wanted to out someone so bad ?

So, there's been so many occasions where I've seen men seeking boyfriend's and husband's on Grindr and other dating sites...but then I'll see them at the grocery store, mall, etc with their wives and two kids and I just feel so bad for their families I get this massive urge to tell them. Of course, I don't say anything. I give them the eye and let them go about their business.There's been times I've seen homophobes, church preachers, etc on these types of gay social media sites and apps and it makes me so angry that they're getting away with it.Anyone else ever felt like this ?
