Define “dogpiling”.
Because if I see a statement I disagree with, I will express that disagreement, regardless as to how many others have already done the same. When you make a post on the internet, you voluntarily expose yourself to others countering you. That’s the nature of online forums. What can you do? You can hold your ground, just like everyone else does when a lot of people disagree with them. The people that make the best posts and defend them against waves of disagreement are the people that become more respected, or in some cases, infamous.
If you cannot handle disagreement, I strongly suggest that you get off the internet.
