You are simply asserting that there is no consensus.  It is clear from the discourse of the person who added the link to the portal that he or she is fine with it being removed.  For some reason, you are more attached to linking the talk page with Christianity, why is that exactly?  Then it is incumbent on you to be fair and add the pages yourself, unless it is YOUR agenda to associate irreligion with Christianity, and thereby take the same ownership that you claim wish to prevent me from asserting.  The only person here making any unilateral judgements is you.
