Without knowing the details of what went on in the house, the simple fact that the bodies were *buried* in an old used septic system, is more than enough to warrant condemnation.
Even if that were the only wrong perpetrated by that group, and I somehow doubt that anyone who would *bury* babies in an old septic system would be paragons of virtue in treating them well in life, it would still deserve condemnation.
All the rest is speculation. The bodies in the septic tank are fact.
Now that Ireland is as infested with various Christ-haters, leftists and Islamists as the rest of the free world no thanks to the EU's social-engineering immigration rules, these ugly and distorted stories have been dug up to make the rounds. Wake up to the reality that you are being manipulated.
