An Apostrophe by Any Other Name

I don't understand how people can think that they can use an apostrophe to make things plural. HOW!? Where did they learn this? "Tomato's" are not tomatoes. An apostrophe is used to show possession or to make a contraction. THAT IS ALL. Never, ever use an apostrophe to make things plural. That shit is obnoxious and it makes the user look like a gaylord.
