That's kind of presumptive and even if your claim could be verified (it really can't), way too many domestic partners have reported violence peaking during The Big Game style events for there to not at least be influence on when their violent outbursts break out, or how often.

It'd be like saying soccer hooligan riots would 100% happen exactly the same way if every single soccer hooligan was collecting stamps instead, while also blissfully ignoring when soccer hooligan riots happen (after soccer games), which isn't just out of thin air.
