Life is indeed unfair because there are many unwritten rules in the society which are unjust to humanity. One major issue is in relation to one's vocation- whether married, single or priest/nun.
What is the unwritten rule? Society will demand and judge you automatically that if you are not a priest or nun, you have to get married or else you are gay or lesbian. Others will even say that if you are "good looking" you are either gay/lesbian or taken. These are toxic ideas or fallacies which are affecting one's mental hygiene or mental health. Society is very cruel. These are not true and people believe it to be true. That's why they marry for wrong reasons and just end up in the statistics of broken marriages which is the trend now.
Society rejected the reality of "Single Blessedness!" Sometimes some think to be single is a misnimer. They simply forget single blessedness is a calling! It is even a choice! Is it hard to believe that there are people who are not really for marriage? Others will say that if you are happy being single why marry somebody you don't even know and take the risk of getting into a relationship which is sometimes bound to fail due to varied reasons?
Sometimes, due to societal pressure, those who are being doubted to be gay or lesbian even if it is not true tend to rebel in the society and so they make it happen.They decided to explore what is this societal prejudice of homosexuality among singles. Sad to say, some enjoyed the thrill/adventure of it and at the end they become gay/lesbian.
People don't get married for so many reasons which narrowminded individuals cannot understand and instead of minding their own business, they will start rumor mmongering or the business of gossip which is very much or highly profitable nowadays. Reasons of poverty, hereditary fatal disease, character/attitude problem and other logical justifications are just being responsible individuals for becoming singles for life. They just don't want to victimize their future children to experience the bad genetics and questionable environment we live in today. This is acceptable which others cannot understand.
It is fearful to marry nowadays because there is an escalating number of married couples undergoing annulment due to reasons they only know. Love is not only the ingredient of long and lasting married relationship. If you cannot supply the financial demands of married life, love will exit and later on annulment will follow or problems of infidelity etc. Gone are the days of our grandparents and parents where fidelity was still at least a value. But in the here and now, we are living in a different world where infidelity is the name of the game. As if, if you are not an infidel, you are not in.
In every vocation, whether you are married, single or priest/nun, there are always advantages and disadvantages. Let us just respect one's vocation and pray for their success and happiness and stop mocking each other's vocation.
"The best is you are preventing the unfair victimization on innocent children." Life is a risk, it is a choice, sad if you are a victim of life you did not choose. Could it be possible? You alone can answer that based from your own experience.
By the way, there are gay priests, lesbian nuns, gay/lesbian married individuals, in other words, just a cover-up of their own homosexuality. Therefore, it is really unfair to single out that singles are homosexuals because they chose not to get married or priest/nun. Sometimes, this judgemental attitude is simply a projection of their own homosexuality.
