Sex, religion, and politics are all "hot button" topics. People often have very strong feelings concerning their views on issues in these 3 categories, so it is often a good idea to steer clear of these categories, to keep a get together from turning into a verbal, or even a physical brawl.
I can pretty much talk to most of my family about most things in these categories, except my sister. Her and her husbands views are very different from the rest of the family. At this point I am the only one left who is still able to talk to my sister, but I know not to bring up these topics. She can be a difficult person to deal with. That's why I was surprised when she finally got married, but her husband is more laid back, and they do get along well, so I am happy for them.
One of life's ironies: My sister and her husband never vote, because there are no candidates who meet their perfection requirements, but they have strong, and complaining views on politics.
My take is: If you don't vote, don't complain. You haven't earned the right to complain.
You have to be careful who you discuss these topics with, as things can sometimes get out of hand. If things seem to be heating up, it's best to change the topic to something safer, or to leave the room, or to leave the place you are at. Too many people today are so lacking in self control, that they will sometimes get physical over a difference of opinion in a discussion. Just this past week I saw a headline about two teenagers who physically attacked each other in a dispute over who made the best Koolaid! And I saw a headline either yesterday or today about two guys who attacked each other in a dispute over who was the better Mexican! So don't take chances. When talk gets heated, change the topic, or leave.
P.S. Don't anyone attack me over this, but in my personal opinion, Koolaid is non nutritional garbage, and tastes like chemicals (to me). With all the real juices out there now, I can't understand why anyone would drink this stuff. So drink real juices, not Koolaid.
