Just as a point of information.
I see, often, that one or another from either side of this debate becomes frustrated with his/her opposition and resorts sometimes to rather harsh and disparaging language.
I just wanted to point out that, while arguing for your position in this debate, it is sometimes productive to address and counter the assumptions, arguments and logic of one's opponents.
For example, in your steadfast conviction that "evening" begins at 6 PM, you may not sway the opinion of another, who is just as certain that "evening" begins at sunset, simply by explaining good points to your own position. By directly addressing what faults exist within the reasoning of your opponent, you give that person the respect for their thoughts and efforts to read and discuss them. Repeating your own opposing position and your reasoning does nothing to highlight any shortcoming within that of your opponent.
Thanks for your patience.
A great evening to all.
