Why does the right complain about the left "virtue signaling", when it's often the right who does so?

My girlfriend before high school, had a friendship with 3 girls. Girl 1 claimed to be bi and later a lesbian but was straight and hung out with homophobic spoiled girls. Girl 2 claimed to be bi too and later an ally but then said she was actually homophobic and Christian. Girl 3 is extremely Christian, all 3 girls are Christian. She is anti-transition, defends Trump, and also wants to mass murder anti-Christians and abolish their religions or lack thereof.

None of these people seem like allies, they seem like virtue signalers.
