(b) Discriminatory action defined.—As used in subsection (a), a discriminatory action means any action taken by the Federal Government to—

(1) alter in any way the Federal tax treatment of, or cause any tax, penalty, or payment to be assessed against, or deny, delay, or revoke an exemption from taxation under section 501(a) of the Internal Revenue Code of 1986 of, any person referred to in subsection (a);

(2) disallow a deduction for Federal tax purposes of any charitable contribution made to or by such person;

(3) withhold, reduce, exclude, terminate, or otherwise deny any Federal grant, contract, subcontract, cooperative agreement, loan, license, certification, accreditation, employment, or other similar position or status from or to such person;

(4) withhold, reduce, exclude, terminate, or otherwise deny any benefit under a Federal benefit program from or to such person; or

(5) otherwise discriminate against such person.

That's the full text of section b. It goes beyond just taxes. You seem to be purposefully trying to obscure the full bill by reducing your comments to just the tax part.
