I would guess he is feeling angry (venting) about how the world is treating his decision.  He wants endorsement, not correction or un asked for guidance of his life. 

People do not like to feel guilty for their choices, even when they know they are wrong.   

Correction for 99% of people is hard to take, some take it harder than others. 

Satin teaches "acceptance" instead of correction of our sins. 

He is simply looking for support of his decision while lashing out against others who tell him the truth.
