It's not being brave, it's being responsible for your own actions.
If you didn't use a throwaway, I'm sure you'd also do a much better job at making your comment a little more eloquent instead of just aggressive and angry.
Posting with a throwaway shows me that you probably don't even 100% believe what you just said.
This is stupid. There are plenty of reasons to post potentially controversial things anonymously, the same reasons against placing a darwin-fish on your car in overly religious regions. None of which have to do with cowardice.
I absolutely agree there are reasons, however this situation has someone acting more belligerent than rational. I personally find hiding anonymously when making such aggressive comments cowardly.
There was a perfectly fine point buried in his original comment, and I personally believe if he had posted with their own account, then they would have taken the time to proof-read and remove the unnecessary emotion and ire from the comment.
