Hello enjoylife and welcome to the BBO forums.
Perhaps you misunderstand the idea behind a 2♥ overcall here. A double shows 9 of your cards, which is pretty good, but nonetheless hides a key feature in the 4th and 5th heart. A heart overcall alone surely shows only 5 cards, which on the surface might seem selfish. However, once followed up by a double you are essentially able to get over approximately 11 cards from your hand including the key features of spade shortage and 5 hearts, which actually improves the level of cooperation between yourself and partner.
You are new here so can be forgiven for thinking that the level is low but in general the BBF posters are a fairly knowledgeable bunch so it would be wise not to assume stupidity in the first instance to a position taken by more than one or 2 respondents. More likely there is a point behind the position that you have not understood and you should use it as a learning opportunity.
Here the choice between double and 2♥ is a close one. It essentially boils down to whether you are willing to double on the second round if it comes back in 3♠. If you are then 2♥ is the more descriptive call; if not then we probably have to double now to avoid losing the opportunity forever. That there are differences of opinion on this is not surprising but to think that either group is making their decision based on selfishness or stupidity is not only insulting but rather completely missing the point. I recommend not calling any other BBF poster stupid (or selfish) again until you are able to spot the crux of the issue on every thread without any doubt about being wrong...
