Good question for Easter-time. Remembering how Jesus suffered may help console you in your suffering. Keep in mind the advance of the gay-agenda is not much compared to being thrown to the lions.
Christians were persecuted for hundreds of years and, in fact, are still persecuted by muslims outside of the U.S..
Putting aside political advice or calls to arms, as a family activity over Easter, maybe you could find some good books on Church history and try to relate it to today w/your family.
Early Christians took some consolation in the Book of Revelations as well, but might be too esoteric of a study for kids.
Note, my lion comment doesn’t mean I think Jesus was thrown to the lions. Early Christians were. That line was probably more appropriate for the subsequent paragraph.
What burns in me is that we are heading to the lions. The homosexuals would already have us in the Colosseum if they could. We still have enough power to stop it. The early Christians couldn’t stop the Romans.
