Before we have a "pile on" a few points...
Not every topic fits neatly in a box that we can all agree on. Some of these topics may become quite heated, folks may be REALLY passionate about them, and opinions may be deeply routed.
For example, the Allegiant Pilots want to get a deal for a contract. Say that doesn't happen and they get released for self help. As they are striking, other members on here cross the picket line and post about it. Are we supposed to still be welcoming of them? Yes it is hypothetical, but plays into what I'm about to say.
Personally, I obviously have strong feelings about Middle East Airlines. I feel they are a huge threat for myself and others on here. After a point, I'm really not going to care if I step on other members toes on here who support these airlines success or think I am wrong. If I cross that invisible line on here in support of my and other's career, internet niceties be damned. I'll be more concerned about my and other's career.
So, as I said, before we have a 'pile on', there is another side.
