It's hard guys, I know.
Sometimes I sit here, just shaking my leg or head, or sometimes both at the same time...lol.
It's fine, natural and healthy to discuss with differing opinions. That's how we increase our knowledge and understanding, and "widen our horizons".
I'm not saying, "You must show agreement in every response...that's supportive. What I'm trying to say is that there's going to be alot of disagreement, but it can be stated respectfully and without flaming/biting comments. Sometimes, at the end of the day, we have to agree to disagree as well.
There will be those times that we're so empassioned about something we disagree with that we're not sure our response won't be biting. It's at those times, we pull away, read a few other threads, take a walk, get a drink, something, then come back and try it again...or decide not to. If ever feeling strong emotion and have concern, don't hesitate to PM a mod or admin to ask their thoughts as well. Threads don't, 99.9% of the time, disappear. One can even reply a week later, so so.
If there's someone that you find has brought about strong negative emotions/reactions time and time again, don't hesitate to place them on ignore. Your experience should be for you, and as you can help/support others...not giving lots of energies in that which is upsetting.
The same goes with forums that just really get under your skin or trigger. A member can choose which forums they want to view.
Make the most of your PC experience by giving/taking what helps and feels positive and refusing what takes energies and creates anxiety or anger. It can really be empowering to actually utilize the tools we have to create our experience here, just as it would be in real life. Feeling empowered, and experiencing the same, was one of the biggest tools that helped me in my healing.
I'm using the "quick reply" so this isn't meant for you, nelleus.

I appreciate your help in making PC a great place with focus on support and healing.
