A lot of people have been discussing this matter and so I feel it is time that I voiced my thoughts on the same. Some of these are not opinions but facts.
Many times when I told people about the Undertaker being the locker-room leader and about the respect which he has back-stage, some people have responded back by saying that he betrayed his wife Sara for Michelle McCool and that he is unethical in having an affair with somebody so young to him. I have read so many articles on the Net discussing this and a lot of fans posting opinions on forums which were so preposterous that some of them said Edge is having an affair with Sara and that is what resulted in his rivalry with Undertaker. Get a life, people!
Now, on what basis can they say that Undertaker betrayed Sara? Did Sara tell them? It is also possible that Sara betrayed Undertaker instead, but you didn't hear the news that way because she is not as popular a public figure as he is (so you heard the news stated in a way that it was revolving around him instead of her). It is also possible that nobody betrayed anyone but they both came to a mutual conclusion that they cannot extend their family-life any further together, so they came to a divorce. How can you make a conclusion without knowing what happened between them? This is the important point - they have legally divorced, and so you don't have any right to question as to what happened in their personal lives, just the way you would not want anyone to peek into your personal lives.
As far as Michelle McCool goes, so what if she is very young compared to Undertaker? Since Undertaker has divorced Sara, he is free to date whom he wants. They are both adults, and it is none of your business as to what 2 consenting adults do!
The bottom-line is - don't meddle with others' "personal" lives (matters and things that don't concern you), let them have their personal space, don't believe in rumours and more importantly don't spread rumours - you know them as wrestlers so be concerned only about their wrestling performance, and mind your own business! For those who think that I am not minding mine by writing about this, such people should mind their's and not even read this. If the others had not started such rumours, I wouldn't have posted this - solve the root of the problem instead of the after-effect.
