Jude 10 "Yet these men speak abusively against whatever they do not understand; and what things they do understand by instinct, like unreasoning animals—these are the very things that destroy them."
Evil often emboldens people. They take a false stance of strength as they attempt to impose their wickedness on others. It is important that we are strong in the faith to stand "toe to toe" with such people. That does not mean that we use the same tactics - Jude mentioned that Michael the Archangel refused to rebuke Satan, but rather turned it over to God - instead we are prepared to not back down. We know who we are and refuse to allow those with carnal motives to push others around without exposing who they are. That was the whole point of Jude's letter 2000 years ago, and it is still a frequent problem today.
