Sorry, I don't have this impression, and I'm not talking about the handful of members that post dozens of pro-BU posts/day (these, probably are paid in some way for it). In the German and Spanish sub-forums some very high-profile members support BU, among them a former Bitcointalk moderator with an important Bitcoin blog. I think it's currently a 60/40 to 70/30 division with the majority being pro-Segwit. In my opinion, in the case of a hard fork, that's not enough to "kill a BTU chain instantly" what would be necessary to preserve Bitcoin's network effect.
The reason those high profile members support BU is very simple - their money lay Not in bitcoins now, but in some altcoins like Eth, dash etc. Even Buterin (guy with some programming skills) mumbles something against Segwit and LN, he understands what it'd mean for his alt.
Consequently they don't want any good for Bitcoin, because if Bitcoin green all forks are red. It means they are not the part of Bitcoin community, even though they supported Bitcoin earlier like Ver. And they don't have bitcoins and they cant dump it, in case of Wu split scenario. (Ver bluffed something about dumping but jumped in the lake very fast, when was being suggested a deal with real bitcoiner)
