A few other things I wanted to mention.
Intention is everything when you're speaking a difficult truth. If you know in your heart that you're not saying it to hurt anyone but to aid evolution and understanding on all sides, you gotta go with the gut. How many times have you heard this advice in your life? Yet it continues to be relevant!
Remember, there is no way to completely avoid hurting anyone. Sometimes your truth will clash with someone else's or inconvenience them. But sometimes it's the only thing which will set you free.
