1) The protests are legal and so is the site. If you go protest, be sure you follow all local and state laws concerning protesting. Some areas prohibit the wearing of masks, so be sure it is ok and do your best to work with the law. This site is legal since it does not endorse, condone, or promote illegal activities. Anybody that tries posting illegal stuff gets their post deleted or modded. Continual abuse gets the user /b/anhammered. 2) All ages, creeds, beliefs, skin colors, sexual orientations and what not is welcome. Granted, again, check your local and state ordinances to see if there are any rules about it. Otherwise, if you have a pulse and you want to join us, you are welcome.
