To be fair, no OT is called "PRO X". They're discussions for very specific topics. It just so happens that anytime there is an OT on something, people who are most interested in that thing spend the most time in there which usually leads to an echo chamber, similar to subreddits. This means any "dissenting opinion" will probably get dogpiled.
You are acting obtuse for no reason. Having an interest in a topic vs. dog piling on dissenting opinions is not the norm of OTs. I can see this if I go into xbox thread and say hey xbox should surely go third party, for example. Then I can see a strong push back because it is a thread for Xbox enthusiasts. It makes sense.
Being interested in an M&A is not what is being displayed in that thread when there are dissenting views. What is displayed there is a vast majority that have created an exho chamber being pro ABK acquisition. Are you seriously pretending otherwise? You think I don't have interest in M&A processes? it's a topic I am very interested in, because of what I do for a living. But I have no interest in going into that echo chamber. It's a waste of my time.
That's the difference. If you want to pretend such dogpiling happens in all OTs, go right ahead I guess.
