Just days after their leader stepped down when a "Hitler selfie" of him went viral, Germany's "anti-Islamization" group PEGIDA marched through Dresden yet again Sunday.

Thousands of people paraded through the streets with signs demanding their chancellor stop letting "followers of Allah" enter Germany, the LA Times reported. While the crowd was massive — at about 17,500 — it was lower than the record demonstration two weeks ago, which drew about 25,000.

The PEGIDA movement — an acronym that stands for Patriotic Europeans Against the Islamization of the West — has held growing weekly marches since October, which began with only 350 people. The founder, Lutz Bachmann, resigned last week after a local newspaper posted a photo of him with a Hitler-style hairdo and mustache.

The co-founder had welcomed Bachmann's decision to step down, particularly since PEGIDA has recently made efforts to distance itself from neo-Nazis who have attended its rallies.

The group may officially claim they are just pushing for tighter immigration regulations into Germany, but many citizens, and even elected officials, have criticized the movement as hateful and dangerous. Germany's foreign minister warned hours before the Sunday march that PEGIDA was tarnishing the nation's image abroad.

"At home we underestimate the damage that PEGIDA's racist slogans and placards already have," the minister, Frank-Walter Steinmeier, told local paper Deutsche Welle.

On Sunday, thousands of people held a counter-demonstration to PEGIDA, following dozens of other marches against the controversial movement.

PEGIDA demonstrators have argued that "Islamization" is threatening the West, and some have completely opposed allowing refugees into Europe.

"They're all idiots and they're planning to make money selling drugs, and they just hang around," one PEGIDA member previously told VICE News of refugees. "They should go back to their countries."
