Ne-Yo is pulling back on his controversial comments about parents who allow their kids to be transgender ... claiming he's always been an advocate for inclusiveness.

The singer said Sunday night, "After much reflection, I’d like to express my deepest apologies to anyone that I may have hurt with my comments on parenting and gender identity."

He also said he's "always been an advocate for love and inclusivity in the LGBTQI+ community, so I understand how my comments could’ve been interpreted as insensitive and offensive."

As we reported, Ne-Yo had folks pretty ticked off by a Saturday interview with VladTV's Gloria Velez, in which he condemned parents who affirm their child's gender identity.

He said he grew up with only 2 genders, and has no problem with others identifying however they want -- but added, "It becomes my business when you try to make me play the game."

He told Gloria, "I feel like parents have almost forgotten what the role of a parent is. If your little boy comes to you and says, ‘Daddy, I want to be a girl.’ And you just let him rock with that? He’s 5. He can’t drive a car yet, but he can decide his sex?"

In his Sunday night mea culpa on X, Ne-Yo added ... gender identity is "nuanced," and he plans to "better educate myself on the topic, so I can approach future conversations with more empathy."
