I know I need to eat food. Now, there's a possability that when I go and make a Peanut Butter and Jelly Sandwich that the nuts MIGHT be affected by some kind of bacterial infrection that could cause me severe illness, or the shrimp I have in the fridge may've been in there too long and spoiled and MIGHT also cause me harm. However, that does not necessarily mean I simply should not eat because these are possabilities that MIGHT happen.
Let us take something from recent times, the Patriot Act.
The Patriot Act provided a much needed upgrade to our intelligence laws, but it also expanded the power of the government. Lets assume however that you felt such a thing was "needed" and "correct".
Lets say however you also agreed with the notion others had that by giving the government more power than inevitably that could be used to give them more power and after that inevitably for a President to declare a state of emergency and become essentially a king.
Does that mean you should not support the Patriot Act, which you strongly and principely felt was a needed and good measure, simply because of something that MIGHT happen in the future if people acted wrongly and twisted it to proportions that it doesn't actually allow?
Not in the least.
That is similar to here.
Many of us feel that marriage between two individuals regardless of sex is correct, right, and constitutional. As such, we support that.
However, the fact that the standard for Equal Protection could maybe somehow possibly be manipulated and wrongly used for abortion doesn't mean I should not support it. It means that if someone tries that I should fight against it.
You should not NOT do something that you firmly believing is right simply because there's some kind of change that someone at some point will try to do something that is not right by manipulating that which you agreed with.
If that is the case, we should never do anything, at any time, because there is ALWAYS a way to create a doomsday scenario where taking any action could cause a bad reaction.
"I am appalled that somebody who is the nominee...would take that kind of position"
"A court took away a presidency"
"...the brother of a man running for president was the governor of the state..."
It's horrifying because Trump is blunt instead of making overt implications.
