I'm not sure what marxism has to do with this (I don't think Marx wrote about charity) and although I'm not a native speaker I'm pretty good at syntax/semantics:
>the solution to guilt is more speech instead of praxis
vs
>the solution to guilt is more speech instead of practice
In English, the usual terms are theory and practice. Praxis is a synonym of practice, but it is rare and formal (for the marxist connection, see https://en.wikipedia.org/wiki/Praxis_School).
At any rate, what you wanted to say is maybe best expressed as "the solution to guilt is more speech instead of action."
I'm well aware of both the colloquial use of practice and "marxist praxis". I was simply implying that, as written, my statement didn't intersect marxism in any way and therefore couldn't have been misunderstood as such without willful misunderstanding.
Note that there are other uses of the word that also themselves don't intersect marxism in any way
>Praxis (from Ancient Greek: πρᾶξις, romanized: praxis) is the process by which a theory, lesson, or skill is enacted, embodied, or realized. "Praxis" may also refer to the act of engaging, applying, exercising, realizing, or practicing ideas.
is exactly what I intended (since I believe pg, and others I was implicating, pontificate but don't do much).
