All across America, planned marches against Sharia law were met by people marching against the protests.
People participating in the counter-protests said demonstrations against Islamic law only served to stoke a distorted view of the religion, the Associated Press reports.
In over 28 cities, including Chicago, Seattle and New York, hundreds of people marched on both sides of the debate. The rallies against Sharia law were organized by ACT for America, which claims Islamic law cannot co-exist with Western democracy.
As AP notes, the majority of Muslims don't want to replace U.S. law with Islamic law.
Some fights did break out. In Seattle, police had to separate the two crowds.
In New York, protestors were divided, with each group on either side of the road.
Counter-protests outnumbered anti-Islamic law marches in some places.
While ACT for America says it opposes discrimination, the Southern Poverty Center, which tracks hate groups, has found otherwise.
In the aftermath of the 2016 election and President Trump's attempted travel bans, reports of anti-Muslim incidents in the U.S. have gone up.
For the most part, the rallies remained peaceful.
