No reason for Catholic schools to have the day off. Public schools are constantly trying to remove the observance of Christian holidays. Catholics could take a stance by not observing secular holidays.
Most Catholics including the clergy are not Catholic anymore. Many
Catholics through the years voted for this oppressive government
we have now. Many will give up their religion than challenge the
government because many depend on the government dole.
This is what the welfare state gradualism has done since the 1930's.
YOUR idea is excellent. I do not think the Bishops have the
courage to propose such an idea,
MLK is looked upon as a Saint that includes majority of Bishop.
They even have a special liturgy on MLK day.
