OK, laugh away and it can be trivial, mountains out of molehills and all of that. I can see that. You can see pigs without relating them to scripture. In fact, you can see Easter dinner without relating it to Christ.
But think of it like this. Easter is about God, and included is "love your God with all your heart, with all your soul, and with all your mind". That is where our mind is on this Easter. What we do, all of our actions, goes into this.
Pigs are in scripture. We are supposed to learn scripture and learn how God used pigs in scripture. We are even supposed to be able to do what God used pigs to represent without using the symbol of pigs. How can we do that if we just make fun of the whole idea?
