Absolutely no one who uses "virtue signalling" on the internet is talking about prayer - from TV preachers or politicians. It's a word typically used associated with a whole set of vocabulary including "woke" and "social justice warrior/SJW". It's meant to deride people talking about diversity initiatives, systemic inequalities, feminism, LGBTQ issues, etc. The explicit implication of the term is that nobody actually genuinely cares about these issues, they just speak about them to virtue signal to their in-group (progressive/left/urban/etc) that they have permissible opinions and that they are not problematic.
