> Are younger lawyers less likely to take cases of clients they deem detestable

If only that. The younger lawyers would attack (sometimes physically, like with Molotov cocktails, as in the case of Urooj Rahman and Colinford Mattis) those they find detestable, and anybody in the law profession that dares to provide them with any service. Which once was considered a basic human right, but not anymore - now, if you defend the deplorables, you become unperson yourself.
