I don't want to get too political here, but it's nearly impossible not to with this Garrett situation.
I feel like there's a big difference between liking a post about a conspiracy theory claiming a Parkland student is a crisis actor versus liking a post mocking Trump for having the words "I hear you" on a notecard as a reminder to be empathetic towards Parkland families. One side is rooted in fiction while the other is rooted in reality. Far too many people unquestionably believe the Parkland conspiracy theories, which also means they would rather think children are actors playing up the severity of a school shooting instead of having empathy and respect for children who just went through a traumatic event where their classmates and teachers were killed. When you're involved in spreading a conspiracy theory attacking a grieving teenager (liking a post helps boost its validity), an apology is necessary. I'm assuming Garrett mindlessly clicked the like button without much thought, but mindless clicks are how those memes spread faster, which then creates an even bigger political divide. There are a lot of Garretts in the world who might be perfectly nice people in front of their friends and family, but they probably don't read much news outside the funny memes they see on their social media feeds, so to them, the conspiracy theories are their reality.
It's difficult to "just listen to what the other side has to say, don't be so PC" when the posts Garrett liked lack basic empathy. The opposite of throwing a child over the border wall is not punishing a child for a decision they were too young to make because their parents forced them to move. The opposite of mocking boys who use makeup, the transgender community, or feminists is not mocking boys who use makeup, the transgender community, or feminists and becoming more accepting of others who aren't like yourself.
If Garret's apology is genuine and he's willing to become more open-minded and listen to Becca, maybe their relationship will last. I honestly don't think Garrett is a bad person, I just think he's ignorant about certain topics and lived a sheltered life where he never had his worldviews questioned before joining the show. I'd like to believe people have a great capacity for change, and if joining The Bachelorette ultimately makes Garrett a more empathetic person and forces him to be more aware of issues in the world outside his Instagram feed, then I might actually enjoy watching this season.
