You are 100% wrong, you need to read my posts again. What I am saying is claiming that it's necessary for safety and using that excuse to do it habitually has no merit. Filtering or splitting where illegal is trading one unlikely threat for another unlikely threat, it's playing "what if" and hand picking what suits your desire to filter or split all the time. I agree that filtering and splitting do have safety and convenience benefits, and are not "cutting line" where legal. It's just not a decision we have the right to make as individuals and is counter productive in the long run.
