In the context of the conversation, the pronoun "they" referred back to Maninthemiddle's "However, some religious teachings do caution against excessive or indulgent pleasure-seeking..." My point being that those labels "excessive" and "indulgent" are self-serving epithets and lies. Not that there cannot be excessive or indulgent pleasure seeking, but what I am saying is that the religious standards for gauging those activities are measured against doctrine, not reality. We see this from various subsects of the Abrahamic religions, Hinduism, and even Buddhists.
The religious based portrayal of activities as being wicked or threatening include (but are not limited to) bans on the ingestion of substances such as alcohol or caffeine; dancing, clothing, contra-doctrinal romantic relationships, contra-doctrinal sexual relationships, availability of education , availability of employment, and approved roles based on the randomness of genes and birth.
