So these people are adventurists. They say "fuck the communists" and call for acts of individualist terrorism. This is anti-Leninist thought. Do not do adventurism.

Here is a work by Lenin where he criticizes adventurism. As example, he criticizes socialist Stepan Balmashov for assassinating Russian politician Dmitry Sipyagin. Lenin writes, "everyone knows and sees perfectly well that this act was in no way connected with the masses and, moreover, could not have been by reason of the very way in which it was carried out—that the persons who committed this terrorist act neither counted on nor hoped for any definite action or support on the part of the masses. In their naïveté, the Socialist-Revolutionaries do not realise that their predilection for terrorism is causally most intimately linked with the fact that, from the very outset, they have always kept, and still keep, aloof from the working-class movement, without even attempting to become a party of the revolutionary class which is waging its class struggle."
