That depends. Has someone you love asked you to attend? If my child were gay and asked me to come see his band play at a pride festival, I would be there.
I’ve never shielded my child from the world. We live in a town that is a tourist town, every weekend there is a festival of some sort and I rarely know which one is going on. Let’s say we decided to go eat down in the historic district and there was a jazz festival or a pride festival or (one we HAVE happened upon) a white pride festival.
We would still walk downtown, still go to eat, we’d still visit a booth and buy a funnel cake or stop and listen to a band or watch a street performer. As long as the group of people is not doing illegal things, becoming violent, etc, we would carry on with our recreation downtown.
On the other hand, if I had a teen who wanted to go out of curiosity, first I would have a long talk and we would remember that people are not zoo exhibits to simply be “looked at”. If their desire was to simply go because they wanted to show respect for people who have been marginalized and hated, I would go with them so we could talk about things.
While I know there are a million vids and photos that give the impression that every pride event is like an orgy, in my personal experience, they are no more raucous than other festivals.
Would I take someone else’s kids without the parents permission, no. Would I force other people to go if they did not want to, no.
Catholics who are going by themselves for example shine their light without a table setup. In what way would they be able to do these things so the receiver knows it was done in Christ’s name?
If I were organizing a group to go, we would have a banner, same one we carry at Pro Life marches or other social-justice events, that has the name of our parish. We have labels that go on the bottles with our social media addresses and the date/times of a group that meets from our Diocese, invite to our adult faith seekers group, etc.
I would wear my T shirt that says “Don’t Judge Someone Just Because They Sin Differently Than You Do” that I bought at a Southern Baptist store.
