Those issues are-(no I am not going to debate any of these issues.If me thinking that only traditional marriage should be legal offends you then too bad)
Gay marriage should be illegal period.
Marijuana should be legal for medicinal and recreational use,including being able to grow it for personal use or even as much as you want.The same rules that apply to alcohol and cigarettes should apply to marijuana.
Prostitution should be legal.If a prostitute is not self employed,meaning she works for a cat house/brothel then there should be laws in place ensuring that she keeps most of the money she makes from selling her services.There should be mandatory weekly or bi-weekly std screenings that the prostitute pays for out of her own pocket unless she works for a business such as a cat house/brothel.There should also be reasonable limits on where she is allowed to sell her services or where a cat house/brothel is allowed to operate.
States should not be allowed to decided on the 2nd amendment since state have proven that many of them only seek to infringe on the constitution which is the supreme law of the land.You should not need a permit/license,register your weapon or go through a waiting period,pay annual taxes, pay excessive sales taxes(taxes higher than the average sales tax for bread,food or books)or submit to a back ground check just to exercise your second amendment rights.The second amendment says shall not infringe at the end of it ,which applies to both of the rights listed in the 2nd amendment.Which is for a regulated militia and for the people the right to keep and bear arms.
Abortion should be illegal on the federal level unless its to save the life of the mother and more than one doctor who is not pro-abortion says that carrying a baby to 50% viable term either through vaginal or c-section birth will result in the loss of the mother's life.
