I've noticed often that when I tried to speak up, people didn't cared about what I was to say. They just made fun out of me pointing errors.
Once you make a grammatical error, people feel like they're free to ignore the rest.

In general, on other forums, on FB, etc. It doesn't happen that often. But still, it happens way often compared to what I'd have imagined.
Unfortunately in Japanese culture it can considered acceptable (and even friendly) to laugh at people in this way. If you hang out with people who understand the pain of language learning (English learners, people with an interest in foreign culture) it's less likely to happen and you'll get empathy instead.
I hope it doesn't discourage you because learning Japanese (or any language) pays off for a lifetime. There is still time to start again.
Anyway, don't let some bad feedback stop you from learning -- use it as inspiration! For every asshole that mocks you, there are 10 more that are willing to help.
Hell, long time ago, when my Japanese was admittedly still pretty bad, I ran into this drunk Japanese dude in some bar with my friend. I spoke in Japanese, and he laughed in my face saying, and I quote exactly, "your Japanese is shit!" I didn't want to counter that his English was just as bad, I just moved on, and kept studying.
There are two types of people in the world: those that lift you up, and those that bring you down -- seek out the former.
Human condition, not so much.
