If you dismiss Antonopoulos because he shitcoins, you are more of a treat to Bitcoin than a help. 

Bitcoin must remain dominant because it makes the best tradeoffs for the most people. It can do this because it has the first mover advantage of the network effect. Any othercoin that copies Bitcoin too closely gets absorbed by Bitcoin. Any coin that differentiates too much, makes compromises in some regard and only fills a niche and lacks liquidity. 

The free market competition is essential in ensuring that Bitcoin adopts the best set of tradeoffs. If we cancel shitcoins and worship Bitcoin as perfected we open it to attacks.
