A lot of it seems to come down to something like Plato was arguing in Philebus:
If you split hairs with words and divide up "types of pleasure" so that you can argue that one type is better than another, then you think you arrive at the conclusion that knowledge about types of pleasure ("knowledge") is more important than pleasure itself. You then start putting "knowledge" on a pedestal instead of "pleasure," and you become a pointy-headed intellectual ivory-tower elitist and you sell admission to the "in-crowd" for a living.
If you in the other hand with Epicurus you honestly and with candor acknowledge that pleasurable feeling (whatever name you want to give it) is the only end result that is desirable in itself, then you end up in the position of the boy who points out to the world that the "emperor has no clothes" and that the "in-crowd" is taking everyone else for a ride.
The choice to go with Epicurus is not only "true" and has many good effects, but it also tends to make the "in-crowd" extremely unhappy, and their unhappiness makes you the perpetual target for ridicule from places like The Atlantic trying to convince you Epicurus was wrong.
Which is why there will also always be a crying need for EpicureanFriends.com and "Pleasure is Not A Four Letter Word" and innumerable other similar responses.
We need to be as organized and energetic as they are.
