I'm new to the forum & having just read through this thread, I have a couple of questions. As was stated earlier, BSA is a uniformed organization, therefore aren't those adults who are registered entitled to wear the uniform? Also, are not all positions held by adults, whether or not they are in direct contact with the boys important? If not, try running a committee with only a SM & a couple of ASMs. Not alot gets done. Keep in mind that some members may not be able to work with the boys (i.e. able to go on campouts, teach MBs, etc)but their behind the scenes work allows the program to continue. Without these individuals the Troop would flounder quickly. Some members on a committee can put in alot of hours, are they not just as entitled to wear the uniform as someone who is out in front? After all the uniform is worn to support the boys and the program.
As far as knots, temp patches, etc., if you've earned them, you have the right to wear them, as long as you wear them correctly! Remember, the uniform represents Scouting and what it stands for, not a display for patches. To me, this is the real issue, that we as Scouters set an example for the boys by wearing the uniform correctly, with the proper patches in their proper places. If we don't wear it right, then how can we expect the boys to do the same.
I also feel that the Centennial Circle should be worn by everyone. The best youth organization for boys has reached a milestone of 100 years and we should celebrate it. Doing so with a patch on our uniform is not excess, egotistical, or bling but rather a sense of pride.
