In revolution, ideologies are thrown out the window and what one does in practice becomes most important. In the spanish civil war you had "anarchists" as ministers in the central government which was crushing the revolution, whereas leninists were fighting alongside other anarchists to defend that very same revolution.
so as to the question
would i, as an anarchist-ish person, shoot leninists?
Depends, if they try fuck up the revolution, yes
