To put it another way, some folks will state sexuality is fluid, but they are inconsistent and believe it only flows from heterosexual to homosexual. To them, stating sexuality can also flow from homosexual to heterosexual is to an impossibility, when we see a growing number of former homosexuals every day.
That last sentence should be:
To them, stating sexuality can also flow from homosexual to heterosexual is an impossibility, when in reality we see a growing number of former homosexuals every day.
