Because personally, I only work with revolutionaries.

It is an ideology which includes only leftists of the revolutionary shade, however is not opposed to cooperated on certain goals with the reformist left.

I'm not working with reformists. Besides this is REVleft, not REFORMleft lol

Perhaps in real life but not here on Revleft.

You work with Reformists constantly, if you are a true Activist. It's kind of unavoidable. It's necessary to achieve concessions for the working class under Capitalism and reformists tend to work for concessions. Within movements like the trade union movement, the feminist movement, and the queer rights movements, the majority are not revolutionaries but will seek concessions favourable to oppressed people.

Pan-leftists are not reformists but revolutionaries, however, we do have to co-operate with reformists when fighting for concessions and not devolve into sectarian idiots.

Yes, there are more reformist leaning people where i lived.

I see it differently. If I am at a rally, yes there are reformists, but that doesn't mean I am collecting signatures for them, or donating to their cause, or even repeating what they say. I am there in unison with a group of people who are protesting something. I am not working against them, but I am not working with them, I am working past them.
The voting both is reformism. But that does not mean I am working with reformists. I am giving my worthless two cents to the government about who I think best represents me. I am giving them my opinion on what option out of two that I don't like, I prefer. I'm not working with them, I'm merely voting because I have the right to. Many live in a reformist system just like a capitalist system. Doesn't mean we are working with it.

Work with reformists can happen up to a certain point. (the point where our interests radically diverge into opposite directions...as in revolutionary and pre-revolutionary circunstances.)
