Logical Fallacies

Ethos:

It is wrong to murder.

For those of us that choose to live by God's standards, it's against the 6th commandment..."Thou Shall Not Kill..."  It's also wrong because it's not up to man but God to choose who lives and who dies.
Murder is stealing another person's right to live, without their consent.
It is also wrong because it is illegal in all fifty states of the US, and every country I can think of at this moment.  It goes directly against the Constitution of the United States which gives us the right to "Life, Liberty, and the Pursuit of Happiness..."
Last but not least, it's pretty socially unacceptable!


Pathos:

Denote $ to save the whales, or these poor cats/dogs, or any other animal on those commercials...

A personal note:  Having a really huge heart for all God's living creatures.  I really wish they'd stop putting those commercials on tv as it makes my son cry every time.
And, that's what they are going for...which I explain to my child every time. 
These ads are meant to appeal to those people who cannot stand to see suffering of any kind.  They display the most pathetic, sickly, underweight animals available to them.  Fact:  before these animals start getting any medical treatment to help their health, they are used to make these commercials.  I guess I see where it would be beneficial but it's that the same thing as all those animals rights activits are fighting against??
They use your pity as a tactic to get you to donate your money.  They use words like compassionate people, which leaves you feeling like a sick jerk if you don't have the funds to send.  Below is one of the favorites I found when searching for some goodies...

"Animals are sentient, sapient, innocent beings. That they should be persecuted, tortured, and murdered - simply for existing - represents the most profane violation of basic morality and decency."

It reminds me of smooth boys I used to date when I was younger.  They would just say about anything to get what they wanted.  Nothing is off limits.  Sorry, best analogy I can think of.


Slippery Slope:

If we pass laws against fully-automatic weapons, then it won't be long before we pass laws on all weapons, and then we will begin to restrict other rights, and finally we will end up living in a communist state. Thus, we should not ban fully-automatic weapons.

You should never gamble. Once you start gambling you find it hard to stop. Soon you are spending all your money on gambling, and eventually you will turn to crime to support your earnings.

If I make an exception for you then I have to make an exception for everyone.
