Gay being an "unhealthy lifestyle" argument?

So basically I'm an out gay teen and my parents don't agree with the "gay lifestyle". I know that we will never see eye to eye with the issue, because they want me to change and not only do I feel it's not possible, but I have no desire to. We get into weekly arguments over the issue and I need help.They always use the argument that the gay life style is an "unhealthy life style", mentioning statistics regarding higher risks of HIV, supposed lower life expectancies. My argument is always that these are just averages and that there is no direct correlation between being gay and the length of your life; yet they don't seem to understand this.Does anyone have any statistics or facts that prove that being gay is not an "unhealthy lifestyle". Or for that matter anything to shut homophobes down in an argumentI'm sorry if this is the wrong sub to ask this sort of question, or if this is a commonly asked thing, I just really need help. I can't argue and fight my parents ever week of my life. Thank you in advance.
