"Your opinion can eat sh*t."
Emily Cave -- the widowed wife of late Edmonton Oilers center Colby Cave -- does NOT want to hear your complaints about COVID-19 protocol ... explaining the alternatives to the safety measures are so much worse.
"My 25 year old husband died alone," Emily said in a powerful statement Thursday.
"I have no clue what his last breath was like. I have yet to have a funeral because of this global pandemic. So for goodness sake, wear a mask. Wash your freaking hands."
As we previously reported, Colby tragically died back in April after emergency surgery to remove a colloid cyst from his brain was unsuccessful.
