OAK CREEK, Wis. (CBS 58) -- The mosque mass shootings in New Zealand bring back painful memories of the Sikh Temple shooting in Oak Creek.

Wade Michael Page, a white supremacist from Cudahy, killed 6 people in the 2012 massacre.

Page then killed himself to avoid arrest.

The founder of the temple was among those killed.

His son says social media is partly to blame for a rise in hate crimes.

"How does divisive conversation online affect communities? It's not just somebody voicing it and saying you know what, I don't like immigrants or I don't like that. But right now, what's happening is those conversations are putting people in danger," said Pardeep Kaleka.

Kaleka founded Serve 2 Unite with a former white supremacist. The group promotes a message of love in the face of hate.

A recent report shows that anti-semitic incidents in the state have increased for the fifth consecutive time and 45% of the incidents happened online.
