Minor Stress

I'll participate! They ask for my opinion because I'm a specialist, but... Even if I give my opinion, I don't have any decision-making power anyway. Actually, even if I state my opinion as a specialist, someone else will say: "But you're doing 〇〇, right?" "Since you're doing 〇〇, isn't this other way better?" "It's impossible, right? Because you're 〇〇? It's meaningless, isn't it?" etc. They completely ignore my opinion and act like I never said anything, so what's the point of me giving my opinion? It makes me wonder. "What's your opinion? Your opinion?" "What's your take as a specialist?" They ask, but then it feels like my answer is meaningless. Do I even need to be there for that discussion? If they're just going to dismiss it as meaningless and proceed with the discussion among a select few under their own leadership, what's the point of asking for opinions in the first place?? Well, it was a stressful workplace incident. I just feel so-so... And apparently, there's another meeting tomorrow, so I have to participate in another pointless discussion... Is this some kind of training?? At this point.
