Do philosophers ever completely agree and should they?

I do not eat animal flesh because I see the clear case that doing so comes at the cost of killing another being that was definitely alive. The other day I was offered a breakfast sandwich that had both egg and turkey bacon on it. I decided to throw away the turkey and only eat the egg (and bread). Also, to add more background to the situation this was a sandwich that would have been eaten by someone else (turkey in all) if I declined. This then led me to think that maybe my actions of throwing away the turkey is actually more morally wrong than eating the turkey. So, my question is if throwing away meat is morally correct for vegetarians (or vegan) who base their diet on the ethical stance of not doing harm to animals.

I am at that age when people try to postpone adulthood (or what is generally conceived as such). This is a time when, if one comes from a developed country, has a lot of money or is educated enough, one has many opportunities to define one’s life. I am from a poor country that suffers from chronic lack of security, spurts of hideous violence and many structural problems, but am educated enough (proof being that I can formulate this question in English, not my mother tongue) to have many opportunities when it comes to my personal/professional development. Among these different opportunities is whether or not I want to reside, and thus work, in my country of origin. Moving away would definitely lead to a richer, easier – though not necessarily happier- life, I am quite sure of it. The problem is I feel an ethical duty to work and live in and for my country. I feel that if every educated person leaves my country, we will be doing a disservice to the place where we and our loved ones are from. Brain drain...

I have been dating a guy for about a year, and the chemical spark has faded for me. How important is this in a relationship? He is a very nice guy and I realize the value of this in a long term relationship.

Do you really believe that the entire universe was made by a "big bang?" Doesn't it seem like there must be some type of higher being something? It just doesn't seem like all the pieces of the puzzle come together from a few dust particles...

Is it morally acceptable to punish? And at what stage does punishment turn to revenge? Comparing something like lex talionis (which seems like revenge) with rehabilitative/correctional systems (which seem restorative), it seems that certain forms of punishment are more ethical than others.

Should the freedoms of religion and speech be more strictly regulated if this freedom is used for such destructive purposes? If so, who has the power to decide what is acceptable?

Do people have a moral obligation to be honest with themselves? Is there anything wrong with priming yourself with delusions in order to experience the bliss of ignorance?

Is there a point at which a person can rightly dismiss a philosophical statement or even an entire philosophical system because it originated with a person of dubious character or intent, but (here's the catch) without committing the ad hominem fallacy in doing so? I am thinking of extreme examples, such as (alleged) philosophical systems created by, say, New Age healers, cult leaders, etc. Or, conversely, would it be necessary even in these extremely examples to address only the philosophical claims made by these movements -- one by one -- instead of addressing the character of the founders themselves in order to avoid the ad hominem?

Why don't philosophers clearly define their terms in relation to the "theist/atheist" debate. Surely before we begin a philosophical discussion we should clearly define our terms; but when it comes to the existence of "God"; both theists and atheists just assume that everyone knows what "God" refers to. Once we have established- when the debate takes place in a Christian context- that "God" refers to the mythological creator deity "Yahweh" of the Bible; is it logical for us to even debate his existence? I mean, we don't debate the existence of the creator deities of African mythology (who have similar properties to the Biblical deity). Could this be a large-scale unexamined cultural bias?
