Would it be OK to ask the democrat congressman/women if they are Shia or Sunni muslim?

That way we could better understand the basis of their political biases. Like why they are for or against the assassination of Soleimani. You would think that a Shia would be automatically and understandably against it. But you would think that a Sunni would be automatically and understandably for it. It looks like Obama is Shia. Giving $150,000,000,000 to Iran by executive decision including $1.5 billion cash from a "secret" government fund without a whimper from Congress.
