Yes, because if you accuse a group when you should be accusing an individual you are doing all of the people in the group a disservice. Then you should just say nothing. 'wie A zegt moet ook B zeggen'. If there are major upsides to this approach then I'm not aware of them, do tell.
Someone else mentioned "the Russian proverb, 'If you've said A, say B'"... In Swedish it's "Har man sagt A får man säga B". Seems rather international.
