“Senator Thompson has said that the federal government should not be involved in the issue of abortion.”
That is because he believes (correctly) that it ought to be a state issue, not a federal one.
You, and Fred, are at odds with the Declaration of Independence, then.
It says that the very purpose of human government is the protection of the God-given and therefore unalienable right to life. Calls it "self-evident," or beyond dispute.
You are also at variance with the Constititution. It says that its very purpose is to secure the blessings of liberty to ourselves AND OUR POSTERITY, ie those not yet born. It also says that the human life cannot be taken without a fair trial, and that no state can allow innocent human life to be taken.
You're also crossways with the Reagan pro-life platform, which proclaims the personhood of the unborn, and their resultant protection by the Fourteenth Amendment.
Do you also believe that states can allow slavery, outlaw free speech, free assembly, free association, the right to keep and bear arms, etc.? You'd have to to remain consistent.
