Worst case is that they have decided that such a ceremony would not be universally popular and potentially open to demonstrations which would greatly detract from the purpose and in particular be upsetting to the RIC descendants (see I do care).

Once upon a time we criminalised homosexuality, we shunned and ostracised unmarried mothers, etc.
Nowadays we just pour scorn on the memories of long dead Irish police officers who, in the main, their biggest crime was following the orders of their paymasters.

I wouldnt be so much worried about SF getting into power on that regard, the people who think this way are already in power.
You must be worried? Although somehow I don't get that from you.
