How do I render multiple lines of HTML in a helper?

I have a helper that looks like this:

if current_user.find_voted_items(vote_scope: :inspired).include?(post)
   link_to vote_inspired_post_path(post, vote_scope: :inspired), method: :post, data: { confirm: 'Are you sure this post Inspires you?' }, class: "btn btn-default" do
    "<i class='fa fa-lightbulb-o'></i> <br />Inspired".html_safe
   end
   link_to vote_happy_post_path(post, vote_scope: :happy), method: :post, data: { confirm: 'Are you sure this post makes you happy?' }, class: "btn btn-success" do
    "<i class='fa fa-smile-o'></i> <br />Happy".html_safe
   end
   link_to vote_disappointed_post_path(post, vote_scope: :disappointed), method: :post, data: { confirm: 'Are you sure this post disappointed you?' }, class: "btn btn-info" do
    "<i class='fa fa-meh-o'></i> <br />Disappointed".html_safe
   end
   link_to vote_upset_post_path(post, vote_scope: :upset), method: :post, data: { confirm: 'Are you sure this post upsets you?' }, class: "btn btn-inverse" do
    "<i class='fa fa-frown-o'></i> <br />Upset".html_safe
   end
end

I need all the links and their nested <i> tags to be rendered - but for some reason, this version is just rendering the last line.

All of that is inside a method called show_vote_buttons(post), that is being called like this in the view: <%= show_vote_buttons(@post) %>

What's the best way to tackle this?
