Completely agree.You know these types of passive aggressive posts are getting really frustrating. These types of threads are often robust and passionate with people with different life experience and viewpoints making contributions.
Reading along and making comments every now and then about how you never comment because someone didn't agree with you is *not* not commenting. It's actually coming across as quite snarky.
There are two ways that these threads can be approached:
1. I stick by my opinion and I don't care what anyone else thinks (which is fine)
2. I stick by my opinion but am willing to learn from and engage with others with differing opinions (also fine)
But with either option people will genuinely be interested in what your viewpoints are, how you come to have them, what information you have to back your claims. That's kind of the purpose of these kinds of threads. In general, where people disagree or react to something that's been said, they try to explain where they are coming from.
If that's not your bag, and for many people it isn't, then I would suggest avoiding these types of discussions.
