Bootstrap 3.3.7 "row" causing horizontal scroll bar

Question

Ok ok, I know. This question has been asked a lot. But, so far, I have not found a working solution. I boiled my page down to nothing but this:

<div class="row">
    <div class="col-sm-12">
        stuff
    </div>
</div>

And there is still a horizontal scroll bar. In dev tools, I can find the row:

.row {
    margin-right: -15px;
    margin-left: -15px;
}

And if I un-click margin-right: -15px; then the problem goes away. But, on my actual page (with all of the content) this creates another problem. The page needs to have zero margins, but it now was a 15px margin on the right.

One of the answers here sad to wrap row with container-fluid. Another said to wrap it in container. Both of these did make the scroll bar go away, but they also give the page side margins, which I can't have.

I've found threads discussing this as far back as 2013. Is this really not fixed yet?

What do I need to do?

First of all you don't need row or col-*12 classes if your section is 100% wide look at this bootstrap example they have not taken any row or col-*12 neither with header nor jumbotron. If your section has column Just take row inside col-* classes for example

<div class="col-sm-6">
    <div class="row">stuff</div>
</div>
<div class="col-sm-6">
    <div class="row">stuff</div>
</div>

Fiddle

Or in case if you are using container-fluid

<div class="container-fluid">
    <div class="row">
        <div class="col-sm-6">
            <div class="row">stuff</div>
        </div>
        <div class="col-sm-6">
            <div class="row">stuff</div>
        </div>
    </div>
</div>
