To be totally honest, it does not matter how uncomfortable others get. It is all about usefulness **or** enthusiasm.
I live in Finland where only 5.3 million people live. From pragmatic perspective, it would not be useful to learn Finnish if I'm going to move out to live my life elsewhere. Now add Finnish sign. It's not like English or C. Learning anything means time investment, and for the learner it should be justified through usefulness or enthusiasm.
