If Republicans support small business why did they block this bill to aid small businesses?

It depends on how you define a small business. Republican like to define a "small business" as any business that has pass through of taxes by the IRS. In other words if the owners can report their business income and expenses on their personal 1040s instead of filing corporate taxes, the Republicans count them as small businesses.

Koch Industries, owned by the two Koch brothers, billionaires in one of the largest privately held energy conglomerates is organized as an S-corp so mainstream Republicans count them as a small Business. When they say, this bill will hurt small businesses, they are referring to businesses like Koch industries, not mom and pop businesses that create 90% of new jobs. Democrats define Small Business by the number of employees and/or the revenue of the business, in other words a real small business, not corporate conglomerates.

Republicans support small businesses much more than Democrats do.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
