I'd still listen to what they have to say, but I'd consider it to be untrustworthy information, as their insult against those who do things differently would tell me that they have a strong enough emotional investment in their decision that they're unable to rationally consider the alternatives.

Either that or they're being manipulative, which is also a big red flag.
