I don't think he is.
All I see is you and a few others defending a symbol of racial hatred.
Since you live in Texas, let's look at part of the Texas Ordinance of Secession from 1861:
"She was received into the confederacy with her own constitution under the guarantee of the federal constitution and the compact of annexation, that she should enjoy these blessings. She was received as a commonwealth holding, maintaining and protecting the institution known as negro slavery–the servitude of the African to the white race within her limits–a relation that had existed from the first settlement of her wilderness by the white race, and which her people intended should exist in all future time. That in this free government all white men are and of right ought to be entitled to equal civil and political rights; that the servitude of the African race, as existing in these States, is mutually beneficial to both bond and free, and is abundantly authorized and justified by the experience of mankind, and the revealed will of the Almighty Creator, as recognized by all Christian nations; while the destruction of the existing relations between the two races, as advocated by our sectional enemies, would bring inevitable calamities upon both and desolation upon the fifteen slave-holding States."
The bolded above is what your Confederate Flag symbolizes, and what the state you live in wanted.
