>They believe that morality is what most people agree on
Whatever mythology or justification people have for their morality isn't actually at issue, it's the actual moral assumptions and beliefs and their results that is.
> Now, they use that to criticize and undermine religion
It is one form of morality declaring its previous model outmoded. Early Christians attacked and undermined other Christians too.

>They say that morality is a social construct and thus relative.
Have you actually thought through what this means, or do you just get upset?
All it takes is to look at animals to see how relative morality actually is, to us, as humans. Why is it a grave sin for a man to kill another man, where a falcon tears into a rabbit, we can't make such moral judgements?

> The reinterpretation of Christ as a communist is intself a relativistic view.
Not what I said, do not be a simpleton. The underlying assumptions within the communistic worldview stem from Christianity, even if it is separated by two or three degrees. The idea of humans possessing some innate "equality" can't be justified through any naturalistic lens.
>The existence of social constructs doesn't make those concepts any less rational or meaningful.
This is a truism
