<human>: Could you distill the essence of the text into 1-3 sentences?

This is a strange one to me as I don't know how to handle it, but also not sure if it is legitimately something of concern or if my other other family (cousins etc) are over sensitive. 

My dad is the most genuine person I know. Very supportive of all of our family. And what's strange is that my black or gay friends have always felt comfortable around him. If they're a friend of mine, he would do anything for them. 

But my dad also likes making jokes and sometimes makes a joke to get a rise out of people - that in appropriate joke. Be it mild racism or homophobic jokes. Usually these are cheek comments to me or my immediate family but they are becoming more prevalent. Any news piece on gays or race will be met with a stupid comment where I think he's just trying to be funny. I try to ignore it but again, he's trying to get a rise out of people. 

So now he has said a few comments in a big shared extended family chat we have going on on Whatsapp. 
Some joke about "equal opportunity team winning the F1". Not even a joke but trying to get a laugh. 

Because he is actually quite generous and would hate to know people are being uncomfortable, or would want them to lightened up because it's just a joke, I'm trying to work out the best way to tell him.
<bot>: my dad makes mild racist/inappropriate jokes despite being a generous and giving person. Making extended family feel a bit uncomfortable.
