Ritual prostitution was common in many ancient religions, and Baal and Asherah were commonly worshipped at the time. It only seems aberrant in hindsight because we live in a world formed from the strict patriarchy and sexual taboos of one specific Semitic religion, and a narrative of history written by its adherents.

That said as far as I know the whole Easter/Eostre connection has been discredited by the actual evidence. Which is unfortunate because it would be such an enjoyable thing to annoy Christians with if it were true.
