Well, this is very good point. I will explain it to you as I have it personally:
On one hand, every time there is a huge stream of anti new gTLD posts in some threads on NamePros, I, and other gTLD investors, we actually have great buying opportunities here. I have bough lot of nice new gTLD domains from members here, for few bucks. People are dropping or selling very cheaply sometimes very good new gTLD names, often after they are reading posts from naysayers. They do not realize that those few people who are constantly posting anti new gTLD posts here are very biased. Nobody from them has any new gTLDs investments whatsoever, no experience, no contacts in this area, absolutely nothing. Just their opinions. Because, opinions are for free, aren't they?
As far as I know, one of them is actually sitting on very nice .com porfolio. Another one spent years to build large ccTLD portolio. There is also a guy who invested about year ago in new gTLD domains, but names he picked were simple one of the worst I have ever seen. He had to drop then all of them, and since then he is saying that new gTLDs does not work. Well it sure has not worked for him. I think my favorite from this small camp is a person who is for long time trying unsuccessfully selling somewhat obscure .link domain, while in parallel he is posting tons of gTLD bashing links in every thread he visits. While I fully understand incentives of other naysayers, I can not simply wrap my mind around this one, I simply does not understand it. But all is ok. I mean, I have my fun here, and I am buying very cheaply. This is one aspect of it.
On the other hand, there is something what is called a morale, or sense of community. If I would be driven only from opportunistic forces, I would join the naysayers and and start bashing too! But I like to also share information and enjoy the people here, and so I sometimes I get into discussions like in this thread, and say my opinion. I am persuaded 100% that new Gs are true opportunity for everyone, and I also believe one should be very careful to listen to people who are heavily investing in com or ccTLDs...do you really think that someone who spent years to build valuable .com portfolio will tell you ANYTHING nice about new gTLD domains which directly threats his or her own business? I particularly do not like some appraisals from senior members, when it comes to new gTLDs..just recently I saw new member here, joined day ago,, he posted pretty valuable new gTLD domains, very nice list..each of them can easily fetch few hundreds to low thousands even in solid new gTLD re seller market (I am not even speaking about end users here)..and what senior member told him (guy who is here from 2003!!!) - he told him his domains are of no value, and he should put them to auction starting $1 to basically get rid of them. If I see this kind of "advice", I interact, because it is a pure disgrace.
I am also biased, as you can see from my portfolio, as I am new gTLD enthusiast.
But, at least I tell it openly, and I do not go to .com and ccTLD threads, and spread my "valuable opinions" there.
So you see, it is kind of ambivalent position here. One one hand, gTLD bashing is great for purchases, but in parallel, one simply does not feel good to listen it all the time.
I hope it helped
