I think they are so fortunate to having loving talented parents (and lovely grandparents, if you follow their whole story) with such talents.
You cant get teenagers boys to publicly join in and sing if they don't want to. There is no evidence whatsoever of duress.
They don't preach hatred.
If you look at their body of work much is tender or just sheer fun. they saw us through Covid.
If you dont like that particular political POV then that is a different matter
-the values in their songs are shared by a great many people who have substantial dislike of the current government.
I think their family values and love shine out. Just look through a few songs and read the comments underneath, especially the early Covid ones. they brought comfort and connection to so many.
