"This genuinely doesn't offend me, coz I'm way too thick skinned when it comes to this kind of sh**," he wrote. "BUT I just wanted to share this with everyone, so you can see how homophobia is still SO PRESENT in our society!!"
This isn't the first time Smith has reacted to anti-gay slurs. In a candid interview with Australia's 60 Minutes, the "Stay With Me Singer" confessed that the jabs about his weight have hurt him more than what's said in regards to his sexuality.
"If someone called me fat, that affects me way more than someone calling me a f----t," he said. "I think just because I've accepted that, if someone calls me a f----t, it's like, I am gay and I'm proud to be gay so there's no issues there. If something calls you fat, that's something I want to change."
