This is basically it. The set of interesting non-scam cryptocoin projects is very small right now. Monero and just a few others pretty much, so the well-deserved attention Monero gets leads to a crowding-out effect. People who are attached to some particular scamcoin or enjoy the scamcoin-of-the-day scene are put off by the reality that a coin that is actually being developed and gaining a following as a genuine open source project gets more lasting attention and discussion than any one particular scam. This makes them resentful and hateful, but nothing we can do about that.  

I think they don't understand that with or without Monero, the scamcoin game is about up and their beloved altcoin community of scammers and willing victims is in the process of destroying itself anyway. We'll just continue pushing forward.
