"How could you say the entire Father's Rights movement is negative and backlash? "
They are known as "backlash" groups to feminism. They blame women and feminists for their problems.
This from Dr. Michael Flood:
"Fathers’ rights groups overlap with men’s rights groups and both represent an organised backlash to feminism. Fathers’ rights and men’s rights groups can be seen as the anti-feminist wing of the men’s movement, the network of men’s groups and organisations mobilised on gender issues."
"Some fathers' rights groups send misogynist messages, use strategies such as harassment, stalking and intimidation, and strive to chip away at programs and services for women and children. They deny the extent of domestic violence and offer sympathy to the perpetrators."
Personally, I have been to their web sites and forums and I have read their hateful messages (women are vindictive liars, women are malicious, we should repeal their vote, men put more into marriage than women, "rape baloney", etc. etc.)
As well, I have been personally attacked by these guys for writing about them. They have sent me nasty profanity-ridden emails, some threatening. Ask anyone who has every written about them....they are well-known for their nastiness.
