You call not wanting to fight a lack of commitment and cowardice. I call it being sensible and not putting myself in a situation where I'm leasts efficient and will probably contribute nothing, and in worst case scenario cause damage. I will not fight on the front-lines. It's not what I'm good at.

I'm calling it an open invitation to everyone else with any kind of hesitations to use the same excuse to never fight. It's a social contagion that reduces people that otherwise would become fighters. It's a position that reduces revolutionary energy rather than increases it.

Given a choice between fighting and not fighting almost everyone will choose not fighting. The choice must be taken away before revolution actually occurs, both in material conditions and socially. The working class must realise that they have no choice.
