"I Stand Sunday" was an anti-gay, pro-Republican rally this past weekend in Houston, Texas, staged by the Christian-based Family Research Council.
The event was centered around five Houston pastors who are trying to overturn a non-discrimination ordinance that protects LGBT people in the city.
The T-shirts also included the web address NoUnequalRights.com, which states, "our basic premise is 'Equal Rights for all, not Unequal Rights for a few.'"
The website also claims that the Houston "mayor and eleven city council members" have placed "the freedom and safety of all at risk" by passing an ordinance earlier this year that banned discrimination against LGBT people.
Some of the speakers at "I Stand Sunday" included Christian anti-gay advocates Jason and David Benham, Fox News host Mike Huckabee, Fox News commentator Todd Starnes, Sen. Ted Cruz (R-Tx.) Alan Robertson and his dad, Phil Robertson.
Phil, who stars on the reality TV show "Duck Dynasty," played on the fears of the crowd that men will be using women's bathrooms in Houston (video below).
According to RightWingWatch.org, Phil said, "For all you ladies in Texas, trust me when I tell you this: When you're seated in your restroom, putting on your Maybelline, when I need to take a leak, I'm not going there."
