How can I respond to someone who says analogy is bad when it's not

My analogy to there ignorant argument was

They said a pencil was the same as wood because pencils come from wood

And I said that's like saying, bread is the same as wheat because bread comes from wheat

They just say it's bad analogy and there's other ways to explain it, when the analogy and how it's said has nothing to do with the argument as long as the analogy is right
