Is it the ultimate religious insult of all time or not?

So, I have been learning about Christianity since January of this year and I saw Jesus Christ around my birthday in March. And I talked to people of different communities and I embraced it in March after realizing it was Jesus Christ himself, son of God. Though that's a separate debate if He is God or son in Nature or in grace.
I live in Muslim country and no I didn't do it for stupid benefits like lots of people do. So, anyways I know devil wants to lead me astray. Finally, today I got the most derogatory and most saddest and painful insult of all time. So, I was watching a prayers channel on YouTube live and some guy from my country was there.
He had the audacity to be such a hypocritical Muslim I cannot believe it.
He was like hey, everyone, love you Kat (the preacher) and then he asked if I was Muslim and I said I left for Jesus Christ and he told me I should go back to Allah and if I think Jesus is Son of God.

Finally he said, Gorray kiea chakkar mein akhirat kharaab na karlo wapis Ajao Allah ki taraf. Translation : Don't ruin your ahirat or heaven and hell due to these white people. It was so low I am still mad about it and just sad. When I was a Muslim God always protected me and even after I became Christian I know He protected me but those around me never accepted I was a Muslim. They just hated it. And here is the hypocrisy, he said he didn't care about anyone. Why do Muslims not care about anyone even their fellow Muslims.
Anyway I am 30+ and it hurt like hell ( we have white people in our country too and I have heard of less derogatory comments on them then on actual white people). Is Jesus Christ only for white people? My Christian non Bio Mom told me I shouldn't do it if it is for her. I didn't do it for her but for myself. Don't people see who are born Christian how lucky they are.

I even ask you Christians, why do you see the reverts with suspicion? It has been so nerve wrecking for me. Aren't black people also Christians?
