That's what we brethren do, help, aid and assist each other.
But something to always remember when dealing with conspiracy theorists. All they are capable of doing is parroting someone else's faulty or biased information, while as a Mason, you are taught to seek out the light of knowledge and form your own opinions.
Also, another important fact to point out to your co-worker is a little history lesson, being that you are in Texas. Ask him how he likes Texas. Then inform him, that just like America, Texas was founded on Masonic principles. Tell him that Stephen F. Austin while considered to be the father of Texas, he also sought to found the first Masonic lodge in Texas through the Grand Lodge of Mexico. Then ask him what he knows about the Battle of the Alamo. Then ask him if he knew that Colonels William Travis, Jim Bowie and Davy Crockett were all Masons. Then go on to tell him that Masonry was so important to Texas, that the Charter for the first lodge was in the saddle bags of, Mason and future President of Texas, Anson Jones during the Battle of San Jacinto. In fact, General Sam Houston the Commander-in-Chief of the Texas Army was also a Mason. Then go on to tell him that Masonry was so important to Texas, that a year after Texas won their independence, a group of Masons meet to organize and elect officers for the Grand Lodge of the Republic of Texas. The met in the then capitol of Texas, Houston. In fact, the met in the Senate Chamber. And that it was such an important meeting that it was presided over by none other then sitting President of Texas, General Sam Houston, arguablely the most important man in Texas. So to recap, Mason, war hero, and President of of Texas, General Sam Houston was presiding of the organizing the Grand Lodge of the Republic of Texas, the Senate Chamber of the Republic of Texas, in the capitol of the Republic of Texas, in the city that bears his name. Makes one wonder what other kind of impact Masons have had on Texas. In America, which is often considered the great Masonic experiment, about 1/4 of the Presidents have been Masons. In the Republic of Texas, all of the presidents were Masons, and so were their vice-presidents. Not to mention, the 4th President of the Republic of Texas who signed Texas into statehood, was also the first Grand Master of Texas. Since becoming a state, the majority of Texas governors have been Masons, along with Govenor Pat Neff also serving as a Grand Master of Texas. But all of that history is probably just Masons trying to over-glorify their importance in Texas history. If Masons were really that important, then there would be more then a couple of our biggest and most important cities bearing their names. Then ask him if he knows the name of the county you are currently in, and then inform him it was named after a Mason, just like the other 243 counties in Texas.
