When I see sacred things mocked, I should follow the examples of my Christian forebears. Peter did not try to "lighten up" by laughing or joking with those that mocked the manifestations of the Holy Spirit. Jesus did not join in downplaying His own divine nature in an attempt to "fit in." Peter did defend the truth, not with railing accusation, but with simple, humble, sincere testimony. Jesus did suffer their mockery without bitterness, and responded by proving He was King by his actions.
When others cast my pearls before swine, I have options. I can get angry with the offenders, I can join the swine, or I can use the opportunity to demonstrate the value of the pearls.
