That isn't what was said.This is the kind of escalating hyperbole we have come to expect from TRAs though.
The fact is your DC may be the most lovely person in the world, genuinely.
But the fact is also that plenty of these TRAs are horrible people screaming abuse at women for daring to exist and wishing awful injuries on them.
And the point stands for mums of boys. Of COURSE your Brian wouldn't go round raping girls - but someone's son does that.
It is lovely for you to be supportive of your child, that is how it should be. But don't make excuses for the bad apples. As pp said: they all have mums who think the sun shines out of their collective arses too. All the mums can't be right all of the time.
