Texas institutions & organizations should seek to decrease excessive “tribalism”. Our fellow Texans are not the enemy.
Tribalism is a double-edged sword -- it can be good (like when we are kind to friends and family, and when we support Houston sports teams) or it can be bad. A tendency to be suspicious of anyone we identify as not being a member of "our" tribe is part of being human. Expecting people to never experience this deep-seated instinct is a waste of time; instead, we need to recognize it and avoid the harm it can cause.
Neighbors that have different religions or skin color or language or culture are nevertheless still members of our "human tribe". We should celebrate the remarkable diversity we see in Texas, and especially in District 13's Houston and Fort Bend communities.
