Sadly, some of the comments from CHL holders that I've seen paint the worst picture of the type of people who choose to carry a concealed weapon. I've seen the rude and relentless bashing of business owners who post signs prohibiting carry on their property. I've seen it go as far as people nit picking the details of the sign such as exact wording, size and font of the lettering, location of posting, etc just to make their point. In Texas, the Penal Code 30.06 sign has some very specific requirements to be considered valid. Some take these requirements way too far and just end up making things more difficult than they should be.
It's a simple matter of respect. If I go somewhere that prohibits me from carrying a weapon, I either willingly disarm or simply choose not to give them my business. In some cases it may be appropriate to inquire as to why the business chose to post the sign and more often than not it's a matter of corporate policy from higher up the chain such as stores like Ikea near my home which recently posted the signs. The point is, I want people to respect my right to legally carry a firearm should I chose to do so in accordance with the law (properly concealed of course) and in return I will respect their rights.
Unfortunately with this topic being one hot political subjects right now, these things aren't always so simple.
