I really doubt that there's anything you could have said that would have had any impact on these guys. One of the guys was perpetually smirking whenever anything related to blockchain technology outside of bitcoin was discussed. I've run into this kind of this mentality before (more in religious areas than in technical areas, ofc) and generally any reasoned argument you try to make will just be ignored or derided.

I'm not saying it's impossible to change someone with this kind of attitude, but it's pretty much impossible to do it in one session, and it's usually going to take arguments from a lot of people they know, since they don't generally have the technical abilities to understand the underlying issues and have to rely on the statements of authorities they trust. Don't get me wrong, I'm not saying this is totally crazy: I don't bother to educate myself in every area of study either and I rely on other people's opinions to some extent in lots of things. But I try to keep in mind when I'm doing that, and keep an objective view when I hear opposition to such opinions (as you suggested at the end there).

The only way someone would react like this is if Steem was a threat to their ecosystem.

Chris DeRose is an idiot, look at this piece he just wrote up in CoinDesk: http://www.coindesk.com/why-you-should-beware-the-altcoin-rebrand/

Nice work trying to keep an open mind and rebut their comments.
They are big guys with big voices and i feel like sometimes you had to fight pretty hard just to get a word in. I hope everything calmed down at the dinner and you were able to relax and enjoy the night. I will shoot you an email about the next BeyondBitcoin hangout (i was waiting for you to do this as it was advertised as your First Talk).
I can promise you a much more relaxed and open environment with some smart and passionate people open to hearing about the news, advancements and goals of all projects including Bitcoin.

It's worth noting that Steem is not a direct competitor to Bitcoin, and actually helps it by introducing new people to crypto.

Completely agree +5%

And steals their money and time, when they could just be using medium.com with less risk and complication

You could say PayPal has less risk and complication than bitcoin, but that's comparing apples to oranges.
