Have you ever even used one? They are nothing like a kitty litter box. I've been in multiple facilities (rest areas mostly) that use them. There's no odor and you use them just like a regular toilet. You claim it's personal choice and as such it's not subject to anyone's criticism, including your comments about "snowflakes". I wonder how many of you that agree ran from changing a diaper! As you also state RVing should be "pleasurable" and some aren't comfortable with the black tank aspect. It doesn't make them a "snowflake"-it makes them "different". Why not try to be supportive of something new instead of critical?
