There are a variety of topics that are discussed on here- dating, clothing, schooling, media exposure, to name a few, where some people say others are "making a big deal out of a small issue". One example from an active thread- not going swimming at the beach because of immodest attire on others. Such a decision is indeed radical in the eyes of our secular society.
Here's a very good sermon on why we should be willing to be "radical" when it is required. In short, the bottom line is the salvation of souls. It does me and my family no good to be popular in this life with the cool crowd if we burn in hell for all eternity.
