Either that or its become like a cult where you can't question anything. Many cults have pointless rituals like mining.
Bingo 
I agree.. I've been debating them non stop for a few days on Bitcointalk and some of them won't budge.
Most think anything that isn't Bitcoin is a scam coin.
Some think that energy has to be consumed in the minting of Bitcoins for them to have any value.
The anarchists seem to really hate DPoS because of the election process.
Some think the exchanges have manipulated the price of PoS coins and this is the only reason for their value.
Others say the rich still get richer because they can vote in delegates controlled by themselves.
A few mentions of DPoS/BitsharesX being like a central bank... we all know how much people hate central banks.
Some think DPoS is subject to social engineering and politics
The point has been made that Delegates likely have less security measures in place and ddos resistance than Bitcoin mining pools.
Some don't understand the need for voting and the reason for only having 101 delegates.
These are some of the most common arguments, and I am not saying they are accurate or I agree with them. Some of the arguments I think I have refuted pretty well, but some just refuse to change their minds no matter what I say.
By the way.. I could use some help in the debate:
