You're right, whatever the Internet might allow us to display, courage is not one of them. Fighting on the Internet does not display anything other than the inability to understand "futility".
Regardless though, we can show character or lack of it. You've shown character here.

Gerard, it is time YOU took responsability for YOUR actions mate.
All isn't lost. gerard still has the opportunity to make everything right. To look deep inside himself, to truly repent, and to stop fighting everyone and himself.
