Roughly 300 Muslims and supporters gathered at the Texas Capitol in Austin Thursday for Muslim Capitol Day - but this year was different. For the first time since its founding in 2003, the annual rally drew a significant number of protesters and opposition.

According to New York Daily News, "a handful of protesters" showed up at Muslim Capitol Day, waving anti-Islam posters and harassing the attendees.

Protesters yelled, "We don't want you here," "ISIS will gladly take you" and other Islamophobic slurs, the Houston Chronicle reported.

As the Council on American-Islamic Relations opened the gathering on the Capitol steps, a protester who had been pretending to be a participant grabbed the microphone. The protester, a fifty-year-old woman from Michigan named Christine Weick, shouted into the mike: "Islam will never dominate in the United States and by the grace of God it will not dominate Texas!"

Muslim Capitol Day began in 2003 but this was the first year it drew significant opposition, Council Executive Director Mustafaa Carroll said. Online threats prompted the council to ramp up security and even call the FBI this year, Carroll added.

The event is an opportunity for devotees to meet with lawmakers. However, freshman Republican Representative Molly White has been criticized for her treatment of Muslim guests: she was out of town on the day but left an Israeli flag in her office. White also ordered her staff to grill visitors about their allegiance to America.

"Ask representatives from the Muslim community to renounce Islamic terrorist groups and publicly announce allegiance to America and our laws," the first-year representative told her staff.

She boasted about the move on her Facebook page.

"If you love America, obey our laws and condemn Islamic terrorism then I embrace you as a fellow American. If not, then I do not," she wrote.

"We will see how long they stay in my office," she added in the Facebook post.

Facebook users quickly called out the representative for her seemingly anti-Muslim comments.

"It's disgusting how you are instigating and trying to put people against each other for political achievement," Faith Einkarem commented on the post, who described herself as a proud Texan and an American Muslim.

"As a Jew, I presume that you expect me to appreciate your use of an Israeli flag. I don't. Your hatred and bigotry are offensive across the range of religions," Matthew Gabriel wrote.

White defended herself by writing on Facebook: "If you love America, obey our laws and condemn Islamic terrorism then I embrace you as a fellow American. If not, then I do not."
